Cool-Fetch: Compiler-Enabled Power-Aware Fetch Throttling

In this paper, we present an architecture-compiler based approach to reduce energy consumption in the processor. While we mainly target the fetch unit, an important side-effect of our approach is that we obtain energy savings in many other parts in the processor. The explanation is that the fetch unit often runs substantially ahead of execution, bringing in instructions to different stages in the processor that may never be executed.
