一种面向能耗的可重构片上统一存储架构
Energy-oriented reconfigurable on-chip unified memory architecture
摘要
Abstract
A dynamic reconfigurable on-chip unified memory hierarchy (RcfgMem) is explored. The given resource of RcfgMem can be divided into certain size of Cache and SPM (scratch-pad memory) by the configuration. And a dynamic configuration management algorithm is provided based on Cache behavior phase graph. The characteristics of program execution are studied and a phase detect logic based on basic block vector is used. The configuration context can be shifted quickly by predicting the program phase. The experiment results show that compared with 4 kB 4-way associate instruction Cache, the total energy consumption can be reduced by 15. 98% on average 34.03% to the utmost without performance degradation.关键词
