An Efficient Architecture Method for Improving Energy Efficiency:Parallel Processing
Yi Huan Hui · Chinese Journal of Computers · 2009
Energy consumption has been paid increasing attention to in the computer domain because of its deep influence on the design of high-performance chips and systems.Many techniques are proposed to improve energy efficiency of computer systems,and in the paper the author focuses on parallel processing on architecture level.Parallel processing improves energy efficiency by using some computing nodes with moderate performance,which maintain high throughput by parallel execution.In this paper,the authors present the fundamental of parallel processing improving energy efficiency,and models the time and energy overhead involved in parallel execution.Based on the models,the author investigates low-voltage parallel systems,parallel systems with dynamic voltage scaling,and multi-core microprocessors,and reveals their potential of improving energy efficiency.
