The winning project, &quot;A Framework for a Relative Real-Time Tracking System Based on Ultra-Wideband Technology&quot;, was conducted as a master thesis in the Embedded Electronic System Design master programme.</b></p> The growing number of applications in automated robots and vehicles has led to an increasing demand for positioning, location and tracking systems. The majority of methods currently in use are based on machine-vision systems, and require a direct line of sight between the tracking device and the target at all times, to carry out the desired functions. This limits the possible applications and makes them vulnerable to disturbances.<br /><br />Gabriel Ortiz and Fredrik Treven have built a prototype for tracking devices, demonstrating an innovative variant of UWB positioning where a set of anchors follows the target's position, and maintains a specific distance to it. This is in contrast to common indoor positioning systems, where the target monitors its own position in relation to fixed reference points. Examples of gadgets that could follow you around in the future are shopping carts, suitcases, as well as various kinds of toys.  <br /><br />The entire thesis is available here<br /><a href="http://studentarbeten.chalmers.se/publication/249921">http://studentarbeten.chalmers.se/publication/249921</a>Fri, 17 Nov 2017 08:00:00 +0100http://www.chalmers.se/en/areas-of-advance/ict/news/Pages/Artificial-Intelligence-Starting-From-a-Blank-Slate.aspxhttp://www.chalmers.se/en/areas-of-advance/ict/news/Pages/Artificial-Intelligence-Starting-From-a-Blank-Slate.aspxArtificial Intelligence Starting From a Blank Slate<p><b>Watch the seminar about the main principles used in AlphaGoZero, developed by Google DeepMind and recently covered in media. We also present research at Chalmers that uses reinforcement learning.</b></p>​ <br />A grand challenge for artificial intelligence is to develop an algorithm that learns complex concepts from a blank slate and with superhuman proficiency. To beat world-champion human players at the classic strategy game Go, Google DeepMInd developed a program AlphaGo, trained through a combination of supervised learning based on millions of human expert moves and reinforcement learning from self-play. This program defeated Go champion Lee Sedol in a tournament in March 2016.<br /><br />A new version of the AlphaGo computer program, called AlphaGo Zero, was able to teach itself to rapidly master Go, starting from a blank slate and without human input, as reported in <a href="https://deepmind.com/blog/alphago-zero-learning-scratch/" target="_blank">a new paper published in Nature on 19 October</a>. It learns solely from the games that it plays against itself, starting from random moves, with only the board and pieces as inputs and without human data. And defeated its predecessor by 100 games to 0 after training for only 36 h.<br /><br />AlphaGo Zero uses a single neural network, which is trained to predict the program’s own move selection and the winner of its games, improving with each iteration of self-play. As the program trained, it independently discovered some of the same game principles that took humans thousands of years to conceptualize and also developed novel strategies that provide new insights into this ancient game.The new program uses a single machine and 4 TPUs while the previous version of AlphaGo was trained over several months and required multiple machines and 48 TPUs (specialized chips for neural network training).<br /><br />We will discuss the main principles and new extensions of reinforcement used in this work and at the end we will  briefly discuss research at Chalmers that uses reinforcement learning in autonomous driving and natural language technology research. <br /><br /><br /><strong>The seminar was held on 10 November 2017</strong><br /><span>Speakers: Devdatt Dubhashi, Mikael Kågebäck and others, Department of Computer Science and Engineering, Chalmers<span style="display:inline-block"></span></span><br />Location: RunAn, Chalmers Student Union Building, Chalmersplatsen 1, Johanneberg<br /><br /><br /><strong>Media coverage:</strong><br />The research paper from DeepMind caused a lot of media attention, also in Swedish media. <br />Chalmers machine learning experts have commented in Swedish media (in Swedish).<br /><ul><li><a href="https://svenska.yle.fi/artikel/2017/10/18/googles-ai-program-larde-sig-sjalv-att-spela-det-svara-bradspelet-go-finlandskt" target="_blank">Devdatt Dubhashi in Yle.</a></li> <li><a href="http://sverigesradio.se/sida/artikel.aspx?programid=406&amp;artikel=6801347" target="_blank">Mikael Kågebäck in Vetenskapsradion i P1</a>, and in <a href="http://sverigesradio.se/sida/artikel.aspx?programid=104&amp;artikel=6801896" target="_blank">P4 Göteborg</a>, also partly available <a href="https://www.facebook.com/P4SRGoteborg/videos/10155704848598529/" target="_blank">on Facebook</a>.  </li> <li><a href="https://www.svt.se/nyheter/vetenskap/artificiell-intelligens-tar-ett-stort-kliv-framat" target="_blank">Mikael Kågebäck in SVT vetenskap.</a>  </li></ul>Mon, 23 Oct 2017 17:00:00 +0200http://www.chalmers.se/en/areas-of-advance/Transport/news/Pages/New-research-opportunities-as-ElectriCity-grows.aspxhttp://www.chalmers.se/en/areas-of-advance/Transport/news/Pages/New-research-opportunities-as-ElectriCity-grows.aspxNew research opportunities for Chalmers researchers as ElectriCity grows<p><b>​ElectriCity, best known for the electric bus 55 in Gothenburg, is much more than just the bus. As the project grows, new exciting opportunities for research appear. Per Lövsund, coordinator for ElectriCity at Chalmers University of Technology, invites Chalmers researchers to contact him with ideas.</b></p><p><br /></p> <p>“We can perform research projects, master and bachelor thesis projects within ElectriCity, and thereby gain better dissemination and utilisation of our results”, says Per Lövsund, who calls on Chalmers researchers to contact him with ideas for new projects.<br /></p> <p><br /></p> <p>ElectriCity is now growing to include for example smaller trucks, such as waste trucks and distribution cars. This means exciting opportunities for several research areas, Per Lövsund explains. Self-driving vehicles, safety, community planning, noise, thermal optimization, control algorithms, vehicle dynamics, development and recycling of batteries and fuel cells, and charging station requirements are some examples of questions from different research fields, all of which can be studied within the framework of ElectriCity.<br /></p> <p><br /></p> <p>Researchers involved in ElectriCity have access to research platforms such as buses and other vehicles. The project’s demo arena also includes the new urban area Frihamnen and the development of south Chalmers Johanneberg Campus, with a stop for the ElectriCity bus. Here, safety aspects and new innovative solutions at the stop and interactions between vehicles and unprotected road users can be studied.<br /></p> <p><br /></p> <p>The fact that ElectriCity enters a new phase has already generated new research at Chalmers.<br /></p> <p><br /></p> <p>“One project about bus trains and one about autonomous docking at bus stops are just about to take off”, says Per Lövsund. “Another project investigates how bus drivers experience the effects of the Volvo Dynamic Steering system.”<br /></p> <p><br /></p> <p>A workshop is planned to be held at Chalmers to formulate projects on low-frequency noise in urban environment, modeling of noise impact and safety issues regarding quiet buses at bus stops.<br /></p> <p><br /></p> <p>“In the long run, perhaps other sectors could be included as well.

The one who finds the smartest method to quickly verify a system becomes highly sought after. Carl-Johan Seger is one of those people.</b></p>​ <br />In 1995, Carl-Johan Seger received a phone call with an offer that would change the direction of his research career at the University of British Columbia. He had only a few days earlier taken up a professor's appointment with so-called tenure, a meriting position.<br />&quot;I started my new position in June 1995 and in September I resigned,&quot; says Carl-Johan Seger, laughing at the memory.<br /><br />The phone call came from the American semiconductor company Intel, who was in great need of his skills.<br />&quot;There was a crisis at Intel. They had just rolled out a new generation of Pentium processors when a serious error in the construction was discovered. The error had escaped Intel's very extensive verification procedures. The final bill landed somewhere in the neighbourhood of 475 million dollar&quot;, he says.<br /><br />The problem was that the traditional verification method did not allow testing of all conceivable values, it could simply not be done within the time frame, even though very extensive verification was carried out.<br /><br /><strong>Mathematical tools for verification</strong><br />Carl-Johan Seger's research is on formal methods, i.e., mathematical tools for analysis and verification of systems. Very useful for verifying hardware – in this case silicon circuits. The tools that Carl-Johan Seger worked with in his research could offer the solution to the precise problems that Intel suffered.<br /><br />&quot;With formal methods, we developed a verification tool that was not only more reliable, we could also perform the verification faster.&quot;<br /><br />As a result, Carl-Johan Seger introduced early formal verification in the development process at Intel. <br />&quot;Early formal verification is extremely important for achieving good results. It is only after we verify that we can know for sure, and can draw conclusions from the work. It is usually said that we learn by our mistakes, and I couldn’t agree more.&quot;<br /><br />At Intel, he created the Forte Formal Verification System, based on his previous research, and the same verification system is still used today, over 20 years later.<br />&quot;If you buy a computer today with an Intel processor, large parts of the processor are verified by this method.&quot;<br /><br /><strong>Return to academia</strong><br />He stayed at Intel for 22 years, and during that time he has published his research with great impact.<br />&quot;It has been fun working in industry, but there is not much long-term research done. In 2006-2007, I was given the opportunity to be a visiting researcher at Oxford&quot;, he says. <br /><br />Perhaps that is where the thoughts of returning to academia took shape? So, when Intel last year announced staff cuts, and launched a retirement package, he took the offer.<br />&quot;Intel's offer turned to those who with x number of years in the company, added with one's own age, summed to the number 75 or higher. And it included me with a 3-month margin.&quot;<br /><br />Carl-Johan Seger is pleased with his choice to return to academia and Chalmers, and the mood is on top during the interview. We wonder, of course, how he experiences the transition.<br />&quot;It's a big change, I cannot say it's neither better nor worse, but on the other hand – it takes a lot of effort and renewal and it makes me feel younger.&quot;<br /><br /><strong>Important part of autonomous systems</strong><br />Carl-Johan Seger is recruited as part of Chalmers activities in the Wallenberg project WASP – <a href="/en/areas-of-advance/ict/research/automated-society/wasp/Pages/default.aspx">Wallenberg Autonomous Systems and Software Program</a>. An important trend along with the development of autonomous systems is the decreasing gaps between hardware and software, we are seeing much more of programmable hardware. There are two very big benefits to doing so – increased performance and reduced energy consumption.<br /><br />&quot;When a large number of sensors are introduced to enable an autonomous system, and all sensors are sending their data to a central processor, it becomes inefficient and slow. Through programmable hardware, or FPGA, Field-Programmable Gate Array, we can introduce more intelligence closer to the sensors&quot;, says Carl-Johan Seger.<br /><br />FPGA are circuits in which the function of the circuit is determined by software. It provides flexibility, you do not necessarily need to re-design your hardware to introduce new functionality – just rolling out new instructions is enough. But there's a big challenge, it gets a lot more difficult to design and verify.<br />&quot;Look at cars for example, they contain many computer-powered features, and it's crucial that the systems respond quickly, never fail and are secured. This is what we are testing using formal methods&quot;, says Carl-Johan Seger. <br /><br />So, what does Carl-Johan Seger think about the future of self-driving vehicles out of a safety perspective? He says that there are several layers of technology in the vehicles – all are not critical systems.<br />&quot;There is a core in the systems that we need to find solutions for, in order for the self-driving vehicles to succeed. The future is about robust technology, but it's also about working out the regulations and what the consequences are if anything goes wrong. The market will determine how big risks that are reasonable to take. If the cost of errors becomes too large then we will not see any self-driving vehicles on the roads.&quot;<br /><br />Carl-Johan Seger points out that autonomous systems are not just about vehicles. We will see all sorts of new services, inspections, deliveries, window cleaning, and a host of applications in industry.<br />&quot;The development of autonomous systems leads to an increasing need to do right from the start – and thus it gets more and more important with verification. It is simply faster and less of a business risk to do it right the first time.&quot;<br /><br /><strong>Back at Chalmers</strong><br />Carl-Johan Seger is now recruited to Chalmers as Professor of Computer Science. Which means he is back at Chalmers where he started his studies in 1981, after nearly 34 years in Canada, the United States and Britain.<br />&quot;I don’t say I'm moving <em>back </em>to Sweden. I've been away for so long, so I say I'm moving to Sweden. It actually makes it a little easier for me.&quot;<br /><br />The first task at Chalmers is to build a verification system. Intel has proprietary ownership of the Forte system, so Carl-Johan Seger could not bring it to Chalmers for further research.<br />&quot;My wife usually says Forte is my fourth child, and maybe there is something to it. I have spent at least as many hours with Forte as with my three children.&quot;<br /><br />However, he has the old system to build on, the one he developed during his time as a researcher before leaving for Intel.<br />&quot;Now we are rebuilding, and this time, of course, it will go much faster because we already know the target.&quot;<br /><br /><br />Contact details: Carl-Johan Seger, <a href="mailto:secarl@chalmers.se">secarl@chalmers.se</a><br /><br /><em>Text: Malin Ulfvarson</em><br /><em>Photo: Anneli Andersson</em>Tue, 17 Oct 2017 09:00:00 +0200http://www.chalmers.se/en/areas-of-advance/energy/news/Pages/UNITED-GRID-Working-on-Digitalised-Electricity-Networks.aspxhttp://www.chalmers.se/en/areas-of-advance/energy/news/Pages/UNITED-GRID-Working-on-Digitalised-Electricity-Networks.aspxWorking on Digitalised Electricity Networks<p><b>​A new cross-disciplinary research project targets the next generation technologies for electricity distribution.

The technology is now finding its way to the market through ZeroPoint Technologies AB,  a startup company founded by professor Per Stenström and his former PhD student Angelos Arelakis.</b></p><img src="/SiteCollectionImages/Institutioner/DoIT/News/Angelos.jpg" class="chalmersPosition-FloatRight" alt="Angelos Arelakis" style="margin:5px" />When Angelos Arelakis began his doctoral studies with Per Stenström at Chalmers in 2010, they sat down to discuss possible topics for the dissertation, and the potential of memory compression came up. Per Stenström suggested &quot;a simple experiment to get things on the road&quot;, and the results of those tests were far beyond all expectations. The research that has followed has now evolved into a promising business concept. <br /><br />Usually the subject of memory compression is about compressing data to be stored or transported without processing. In modern computers arithmetic operations are performed in the CPU, which means that data must be fetched from memory when calculations are to be made, traffic that costs both time and energy. The new technology developed at Chalmers handles active data, while it's being processed. <br /><br />&quot;The benefit of the technology is increased memory capacity, but also increased CPU and memory throughput, which basically will lead to improved performance without affecting the physical size of the memory, or the energy consumption,&quot; says Angelos Arelakis. <br /><br />He left Chalmers earlier this year to become chief system architect at ZeroPoint Technologies AB, the company he founded with Per Stenström in 2015, with the goal of commercializing the technology he developed as a PhD student. The company aims to release its first product on the market in 2017, and as the technology can be applied to all types of data, the potential customers are companies that deal with everything from smartphones to major computer centers. Already in the early research results, Per Stenström anticipated future commercial opportunities, and the first patent application was filed in 2012. Since then, six more applications have been submitted, and the first patent has been granted. <br /><br />Solutions that improve storage capacity through different compression systems and methods are already on the market, some are even fast enough to also provide improved memory capacity. What's unique with the technology from Zeropoint is the combination of speed, intelligent compression and generality. Because the compression algorithms are implemented in hardware logic rather than in the software, they become extremely fast, and the software developers can continue as usual without the need for any adjustments. The company has evaluated various applications in collaboration with several international IT companies. <br /><br />&quot;There is no golden business model, you need to do trial and error. We have taken different applications to some potential customers, and they need to verify that the technology works. If it doesn't make sense, it's not meaningful to proceed. The product we are closest to launching now is a licensed IP core,&quot; says Angelos Arelakis. <br /><br />ZeroPoint Technologies AB has received start-up contributions from, among others, Chalmers Ventures and Qamcom, to take the product to the market. Angelos Arelakis has also been awarded a scholarship from <em>King Carl XVI Gustaf's 50th birthday foundation for science, technology and the environment</em> to further develop his research. The company currently employs about 8 people, but recruits continuously for new positions. The research at Chalmers was conducted within the project Euroserver, in EU FP7. <h3 class="chalmersElement-H3">Contact </h3> <div>Angelos Arelakis, <a href="mailto:angelos.arelakis@zptcorp.com">angelos.arelakis@zptcorp.com</a> <br />Per Stenström, <a href="/en/departments/cse/calendar/Pages/per.stenstrom@chalmers.se">per.stenstrom@chalmers.se</a></div> <div><br /></div> <div><h3 class="chalmersElement-H3">Related links</h3></div> <div><a href="http://www.euroserver-project.eu/">ZeroPoint Technologies AB</a> <br /><a href="http://www.euroserver-project.eu/">The EU-project Euroserver</a> </div> Mon, 10 Jul 2017 00:00:00 +0200http://www.chalmers.se/en/areas-of-advance/ict/news/Pages/The-second-call-for-WASP-PhD-student-positions-is-now-open.aspxhttp://www.chalmers.se/en/areas-of-advance/ict/news/Pages/The-second-call-for-WASP-PhD-student-positions-is-now-open.aspxThe second call for WASP PhD student positions is now open<p><b>​Wallenberg Autonomous Systems and Software Program (WASP) announces 22 new PhD student positions.

Even traditionally simple objects such as step counters, thermostats, and light bulbs begin to enjoy wireless communication. On the other hand, many applications are not simple, they are extremely mission and safety-critical. A wireless glucose sensor must quickly and reliably exchange information with, for example, an insulin pump to ensure a patient’s well-being, and two autonomous vehicles approaching an intersection must coordinate and decide within a split second which car shall cross first.<br /><br /><div><img src="/SiteCollectionImages/Institutioner/DoIT/News/olaf.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px;width:160px;height:212px" />Olaf Landsiedel, associate professor in the Networks and Systems division at Computer Science and Engineering, was recently awarded the SSF grant “Framtidens forskningsledare” for the project “Ultra Low-Latency, Low-Power Wireless Mesh Networks”. Current approaches in wireless networking maintain routes in the network, and external factors such as interference and mobility affect these routes, and will force the network to constantly repair them. If a route cannot be repaired sufficiently fast, messages will be delayed, and potentially lost. </div> <div> </div> In the project, which is based on many years of research, Olaf Landsiedel and his colleagues will work on a novel approach, taking on the challenge of exploiting the physical phenomena of the capture effect (the fact that when two signals are present, one will with a higher probability catch the stronger of the two) to design a communication scheme that will ensure that if there is a route towards a destination, it will be found instantly, regardless of the external factors. <div> </div> <div>“With this approach, we want to take existing algorithms that work in, for example, the data center world, where they have significantly more compute power, bandwidth and energy, and redesign these algorithms so they can be employed in the much smaller sensor networks, and operate – on batteries – with very limited compute power and bandwidth” says Olaf Landsiedel. </div> <div> </div> <div> </div> <div> </div> <div><strong>Contact</strong></div> <div>Associate Professor Olaf Landsiedel, Networks and Systems division, Computer Science and Engineering.</div> <div><a href="mailto:olafl@chalmers.se">olafl@chalmers.se</a>​​​</div> <div>Phone: +46 31 772 10 96<br /><br /><a href="http://stratresearch.se/en/">Swedish Foundation for Strategic Research</a><br /><a href="http://stratresearch.se/pressmeddelande/240-miljoner-till-framtidens-forskningsledare/">Press Release in Swedish &quot;Framtidens forskningsledare&quot;</a><br /><br /></div> <div> </div> Wed, 21 Dec 2016 00:00:00 +0100http://www.chalmers.se/en/departments/cse/news/Pages/FacebookSabelfeld.aspxhttp://www.chalmers.se/en/departments/cse/news/Pages/FacebookSabelfeld.aspxFacebook awards Chalmers web security research<p><b>Facebook has acknowledged the work of Chalmers researcher Andrei Sabelfeld and his team, supporting research on improving the security of browser extensions.</b></p><img class="chalmersPosition-FloatRight" src="/SiteCollectionImages/Institutioner/DoIT/News/FacebookAndrei5.gif" alt="" style="margin:5px;width:400px;height:273px" />Chalmers researcher Andrei Sabelfeld received an e-mail reading &quot;We have decided to give you an unrestricted gift of <span></span><span style="display:inline-block"></span>$ 30,000&quot;. Not an entirely unusual sentence in the days of frequent Internet fraud, but this time it proved to be true. The mail came from Facebook, and the research project which they have taken an interest in aims to develop tools that will enable websites to detect whether visitors have browser extensions installed. <br /><br />“Browser extensions provide a powerful platform to enrich browsing experience. At the same time, they raise important security questions. From the point of view of a website, some browser extensions are invasive, removing intended features and adding unintended ones” says Andrei Sabelfeld. <br /><br />In some aspects the interests of the involved parties (users, website owners and providers of browser extensions) collide. The user installs extensions for their needs and wants, which may be the use of smileys, to block ads, keep track of passwords for different sites and services and so on. The provider of extensions may want to be able to assure the user that the extension works to, for example, block all ads. On the other hand, anyone with a website that provides a service may want to be able to control what happens in the visitor's browser. A bank or authority may not want an extension to handle their data, and Facebook, for example, may not want an extension to take control over which ads should be displayed. <br /><br />“We will develop the dual measures of making extension detection easier in the interest of websites and making extension finding more difficult in the interest of extensions” says Andrei Sabelfeld “and in the next step we will investigate a browser architecture that allows a user to take control in arbitrating the conflicting security goals.” <br /><br />This means that for example a bank may request to be very restrictive, and only allow certain extensions, denying all others. In that case, the browser will present the user with the option to run only the permitted extensions, and disable all others for that site. <br /><br /><strong>​<br />Contact</strong><br />Professor Andrei Sabelfeld, Software Technology division, Computer Science and Engineering.<br /><a href="mailto:andrei@chalmers.se">andrei@chalmers.se</a>​​​<div>Phone: +46 31 772 10 18</div> Sun, 11 Dec 2016 00:00:00 +0100http://www.chalmers.se/en/areas-of-advance/ict/news/Pages/WASP-pre-announcement-IndPhDs2017.aspxhttp://www.chalmers.se/en/areas-of-advance/ict/news/Pages/WASP-pre-announcement-IndPhDs2017.aspxPre-announcement: WASP Industrial PhD student positions<p><b>​WASP will open the second call for Industrial PhD student positions 24 January 2017.</b></p>​<strong>Timetable</strong><br />Opening date:  2017-01-24<br />Application due date:  2017-03-31<br />Date of decision:  2017-06-08<br />Earliest start:  2017-08-01<br />Preliminary 15-20 industrial PhD positions are foreseen for this call.<br />Details concerning the application process will be posted in connection with the opening of the call.<br /><br />Source: <a href="http://wasp-sweden.org/pre-announcement-wasp-industrial-phd-student-positions/">http://wasp-sweden.org/pre-announcement-wasp-industrial-phd-student-positions/</a><br />Chalmers contacts: David Sands &lt;<a href="mailto:dave@chalmers.se">dave@chalmers.se</a>&gt; and Christian Berger &lt;<a href="mailto:christian.berger@gu.se">christian.berger@gu.se</a>&gt;<br />Fri, 02 Dec 2016 08:00:00 +0100http://www.chalmers.se/en/departments/cse/news/Pages/ExcessFinal.aspxhttp://www.chalmers.se/en/departments/cse/news/Pages/ExcessFinal.aspxNew approach to computing boosts energy efficiency<p><b>​A European research project led by Chalmers University of Technology has launched a set of tools that will make computer systems more energy efficient – a critical issue for modern computing. Using the framework of the project programmers has been able to provide large data streaming aggregations 54 times more energy efficient than with standard implementations.</b></p>Energy consumption is one of the key challenges of modern computing, whether for wireless embedded client devices or high performance computing centers. The ability to develop energy efficient software is crucial, as the use of data and data processing keeps increasing in all areas of society. The need for power efficient computing is not only due to the environmental impact. Rather, we need energy efficient computing in order to even deliver on the trends predicted. <br /><br />The EU funded Excess project, which finishes August 31, set out three years ago to take on what the researchers perceived as a lack of holistic, integrated approaches to cover all system layers from hardware to user level software, and the limitations this caused to the exploitation of the existing solutions and their energy efficiency. They initially analyzed where energy-performance is wasted, and based on that knowledge they have developed a framework that should allow for rapid development of energy efficient software production. <br /><br />“When we started this research program there was a clear lack of tools and mathematical models to help the software engineers to program in an energy efficient way, and also to reason abstractly about the power and energy behavior of her software” says Philippas Tsigas, professor in Computer Engineering at Chalmers University of Technology, and project leader of Excess. “The holistic approach of the project involves both hardware and software components together, enabling the programmer to make power-aware architectural decisions early. This allows for larger energy savings than previous approaches, where software power optimization was often applied as a secondary step, after the initial application was written.” <br /><br />The Excess project has taken major steps towards providing a set of tools and models to software developers and system designers to allow them to program in an energy efficient way. The tool box spans from fundamentally new energy-saving hardware components, such as the Movidius Myriad platform, to sophisticated efficient libraries and algorithms. <br /><br />Tests run on large data streaming aggregations, a common operation used in real-time data analytics, has shown impressive results. When using the Excess framework, the programmer can provide a 54 times more energy efficient solution compared to a standard implementation on a high-end PC processor. The holistic Excess approach first presents the hardware benefits, using an embedded processor, and then continues to show the best way to split the computations inside the processor, to even further enhance the performance. <br /><br />Movidius, a partner in the Excess project and developers of the ​<a href="http://www.movidius.com/solutions/vision-processing-unit">Myriad</a> platform of vision processors, has integrated both technology and methodology developed in the project into their standard development kit hardware and software offering. In the embedded processor business, there has been a gradual migration of HPC class features getting deployed on embedded platforms. The rapid development in autonomous vehicles such as cars and drones, driving assist systems, and also the general development of home assist robotics (e.g. vacuum cleaners and lawnmowers) has led to the porting of various computer vision algorithms to embedded platforms. Traditionally these algorithms were developed on high performance desktop computers and HPC systems, making them difficult to re-deploy to embedded systems. Another problem was that the algorithms were not developed with energy efficiency in mind. But the Excess project has enabled and directed the development of tools and software development methods to aid the porting of HPC applications to the embedded environment in an energy efficient way.<br /><br /> <h4 class="chalmersElement-H4">About EXCESS</h4> EXCESS consortium unites Europes leading experts in both HPC and embedded computing.
