Leakage energy optimization for caches has been the target of much recent effort. In this work, we focus on instruction caches and tailor two techniques that exploit the two major factors that shape the instruction access behavior, namely, hotspot execution and sequentiality. First, we adopt a hotspot detection mechanism by profiling the branch behavior at runtime and utilize this to implement a HotSpot based Leakage Management (HSLM) mechanism. Second, we exploit code sequentiality in… CONTINUE READING
