Power efficient instruction cache for wide-issue processors

The paper focuses on reducing power in instruction cache by eliminating the fetching of instructions that are not needed from a cache line. We propose a mechanism that predicts which instructions are going to be used out of a cache line before that line is fetched into the instruction buffer. The av...

Zusammenfassung:The paper focuses on reducing power in instruction cache by eliminating the fetching of instructions that are not needed from a cache line. We propose a mechanism that predicts which instructions are going to be used out of a cache line before that line is fetched into the instruction buffer. The average instruction cache power savings obtained by using our fetch predictor is 22% for SPEC95 benchmark suite.
