The paper entitled as FAcET: Fast and Accurate Power/Energy Estimation Tool for CPU-GPU Platforms at Architectural Level authored by Santhosh Kumar Rethinagiri, Oscar Palomar, Javier Arias Moreno, Osman Unsal and Adrian Cristal has been nominated the Best Paper Award at IEEE-SoCC 2015. This paper proposes a powerful power estimation tool at the system-level and a necessary tool for both application and architecture designers.

 

Abstract the paper:

This paper proposes a novel fast and accurate architectural-level tool to estimate power and energy (FAcET) for heterogeneous (CPU-GPU) system architecture based platforms. FAcET consists of two components. The first is a set of generic parametrizable power models generated by characterizing the functional-level activities for different blocks of the chosen platforms. The second is a simulation-based architectural-level prototype that uses SystemC (JIT) simulators to accurately evaluate the parameters of the corresponding power models of the first component. The combination of the two components leads to a novel power and energy estimation methodology at the architectural level that provides a better balance between speed and accuracy. The efficacy of the FAcET tool is verified against measurements taken on real board platforms, which consist of low-power ARM quad-core processors (Cortex-A7, -A9 and -A15), NVIDIA GPUs (Quadro 1000M, Quadro FX5600, Tegra K1, and GTX480) and heterogeneous platforms (NVIDIA Tegra3 and NVIDIA Jetson TK1). Power and energy estimation results obtained with FAcET deviate in less than 3.6% for quad-core processors, 6.5% for GPU, 10% for heterogeneous multiprocessor based systems from the measurements and estimation is 15x faster than state-of-the-art tools.

 

About the conference:

In its 27 years of history, the IEEE International System-on-Chip Conference (SOCC) has been the premier forum for sharing advances in system-on-chip (SoC) technologies, designs, tools, test, verification and applications. Held at changing locations in the USA, Europe and Asia, SOCC is attracting researchers and engineers from all over the world to exchange knowledge, share experiences and establish collaborations with colleagues. Each year, the IEEE-SoCC Programme Committee selects 3 papers to be nominated for the best paper award across 300˖ papers.
