The Effect of Core Number and Core Diversity on Power and Performance in Multicore Processors

摘要: Today, multi-core processors dominate server, desktop and notebook computer’s market. Such have been able to decrease power consumption thermal challenges that designers face within single core processors. In order improve processor’s performance, should choose the best set of cores based on execution delay. this paper, we study several architectures are composed a configurable number cores. We use three with different levels performance consumption. Then, implement configurations processor. each configuration, which has cores, run benchmarks various numbers simultaneous threads, from 1 up 32. Power delay configuration measured. It shown is heterogeneous processor 16 in our bounded area. examined ways threads can be assigned configuration. for serial workloads choice high but parallel consist multiple mixture gives performance.
