Title:

Energy Efficient Network-on-Chip with Runtime Optimization Selection for MPSoCs

Abstract:

Networks-on-Chips (NoCs) play important roles in modern and future manycore processor SoCs as they are highly related to both performance and power consumption of the entire chip. So far, many optimization techniques have been developed to improve NoC's bandwidth, latency, and energy efficiency. However, how energy efficiency is affected with these optimization techniques is not easy to be determined since each of these optimization techniques comes with its own benefits and overheads. Thus, here comes the challenge of when and how such optimization techniques should be applied. In order to solve this problem, we build a runtime framework to throttle these optimization techniques based on performance and energy models. With the help of this framework, we can successfully establish adaptive selections over multiple optimization techniques to further improve performance or energy efficiency of NoCs.
