A New Capacity Co-allocation Algorithm of Split Cache
Xiaoxi Ren · Journal of Hunan University · 2009
Caches compose larger and larger proportion in the power consumption of embedded processors.Based on the fact that different programs need different sizes of instruction and data cache,a new capacity co-allocation algorithm was proposedr.This algorithm can dynamically adjust the configuration of level 1 cache by balancing the instruction and data cache requirement.Mibench simulation results indicate that,compared with the capacity co-allocation cache and the normal cache,the average energy consumption decreases 29.10%,while the average energy delay production improves 33.38%.
