Aamodt, Electrical and Computer Engineering Supervisor Steve Wilton, Electrical and Computer Engineering Supervisory Committee Member Alan Hu, Computer Science University Examiner Andre Ivanov, Electrical and Computer Engineering University Examiner John Owens, The University of California-Davis, Electrical and Computer Engineering External Examiner Additional Supervisory Committee Members: Sidney Fels, Electrical and Computer Engineering Supervisory Committee Member ii Abstract Mobile SoCs have become ubiquitous computing platforms, and, in recent years, they have become increasingly heterogeneous and complex. A typical SoC to- day includes CPUs, GPUs, image processors, video encoders/decoders, and AI engines. This dissertation addresses some of the challenges associated with SoCs in three pieces of work. The first piece of work develops a cycle-accurate model, Emerald, which pro- vides a platform for studying system-level SoC interactions while including the impact of graphics. Our cycle-accurate infrastructure builds upon well-established tools, GPGPU-Sim and gem5, with support for graphics and GPGPU workloads, and full system simulation with Android.

  • Energy-Efficient Mobile GPU Systems
    Energy-Efficient Mobile GPU Systems Jose Maria Arnau Doctor of Philosophy Department of Computer Architecture Universitat Politecnica de Catalunya 2014 2 Abstract The design of mobile GPUs is all about saving energy. Smartphones and tablets are battery-operated and thus any type of rendering needs to use as little energy as possible. Furthermore, smartphones do not include sophisticated cooling systems due to their small size, making heat dissipation a primary concern. Improving the energy-efficiency of mobile GPUs will be absolutely necessary to achieve the per- formance required to satisfy consumer expectations, while maintaining operating time per battery charge and keeping the GPU in its thermal limits. The first step in optimizing energy consumption is to identify the sources of energy drain. Previous studies have demonstrated that the register file is one of the main sources of energy consumption in a GPU. As graphics workloads are highly data- and memory-parallel, GPUs rely on massive multithreading to hide the memory latency and keep the functional units busy. However, aggressive multithreading requires a huge register file to keep the registers of thousands of simultaneous threads. Such a big register file exceeds the power budget typically available for an embedded graphics processors and, hence, more energy-efficient memory latency tolerance techniques are necessary. On the other hand, prior research showed that the off-chip accesses to system memory are one of the most expensive operations in terms of energy in a mobile GPU. Therefore, optimizing memory bandwidth usage is a primary concern in mobile GPU design. Many bandwidth saving techniques, such as texture com- pression or ARM's transaction elimination, have been proposed in both industry and academia.
