Graphics researchers at Samsung Electronics UK have teamed up with mobile graphics specialists Codeplay, Think Silicon and TU Berlin to develop a tool for enabling smartphone batteries to last longer while running advanced video games and using the camera.
The EU Commission has awarded a European GPU consortium a grant of 2.97 million Euros to research and develop a novel tool chain for analysing, visualizing, and improving the power efficiency of applications on mobile Graphics Processor Units (GPUs).
The consortium includes three European technology companies: Codeplay, the Edinburgh based GPU technology company, Think Silicon (a Greek low gate-count Graphics Semiconductor IP Core company) and Samsung Electronics UK Ltd. TU-Berlin (Germany), a European University, completes the group.
The key objectives of the 2 and a half years research project are:
- Define new industry standards for resource and performance monitoring to be widely adopted by embedded hardware GPU vendors (Khronos group)
- Define a methodology for accurate power estimations for embedded GPU.
- Enhance existing Dynamic Voltage and Frequency Scaling (DVFS) mechanism for optimum power management with sustained performance.
- To improve the power efficiency of compute and graphics applications running on mobile GPUs
- Build a unique power and performance visualization tool which informs application and GPU device driver developers of potential power and performance improvements.
Andrew Richards, Codeplay CEO said:
“Working within this expert team across business and academia to analyse power consumption of videogames and camera processing is a fabulous opportunity for us at Codeplay. It will enable us to solve a very challenging problem: lengthening battery life of smartphones while running the most advanced graphics processing.”
Ben Juurlink, project coordinator and professor at TU Berlin, adds:
“Searching for the performance and energy bottlenecks in applications running on embedded GPUs is like searching for a needle in a haystack. It is absolutely crucial that application developers are supported in this challenging task by smart analysis and visualization tools. Current embedded GPUs are powerful enough to execute immersive applications that we could only dream of a few years ago. However, all this compute power is good-for-nothing if the battery lasts for a few minutes only.”
Philip Harmer, of Samsung commented:
“Consumers have become used to powerful, responsive graphics in mobile phones. They now rightly expect long battery life too. The LPGPU2 project will provide an advanced analytic tool for developers to improve the power usage and performance of their applications.”
Dr Iakovos Stamoulis, Think Silicon CTO adds:
“The severely constrained power budget of new mobile and IoT/wearable devices with rich immersive multimedia capabilities shifts the design focus from performance to power in order to meet the toughest specifications. It is of absolute importance to holistically optimize systems at all levels: hardware, algorithmic and application software to minimize power consumption. LPGPU2 Project will provide the means to measure, explore and identify energy usage, which is of utmost importance to achieve the required efficiency.”
About TU Berlin – http://www.tu-berlin.de
TU Berlin looks back at a long and distinguished tradition of teaching and research. In 1799 its most important predecessor, the Building Academy, was founded. In 1946 the university was re-established under the name of Technische Universität Berlin. The seven Faculties of the university offer 100 courses of study from the fields of engineering and natural sciences, economics and business, planning sciences, humanities and the social sciences. Enrolment at TU Berlin is about 32,000 and about 315 professors and an academic staff of 2,600 instruct the students, making it one of the largest technical universities in Germany.
TU Berlin participates in the project through the Embedded Systems Architectures (Architektur eingebetteter Systeme, AES) laboratory of the School of Electrical Engineering and Computer Science. The AES laboratory investigates and teaches the field of computer architecture, ranging from low-power embedded systems to massively parallel high-performance systems. Its current research focuses include multi-/many-core architectures and GPUs, development and optimization of highly scalable parallel applications, and (architecture support for) parallel programming models. More information on the AES laboratory is available at http://www.aes.tu-berlin.de/en.
