Pipeline Gating: Speculation Control for Energy Reduction
Branch prediction has enabled microprocessors to increase instruction level parallelism (ILP) by allowing programs to speculatively execute beyond control boundaries. Although spe...

Performance-aware speculation control using wrong path usefulness prediction
Fetch gating mechanisms have been proposed to gate the processor pipeline to reduce the wasted energy consumption due to wrongpath (i.e. mis-speculated) instructions. These scheme...

Fetch Gating Control Through Speculative Instruction Window Weighting
In a dynamic reordering superscalar processor, the front-end fetches instructions and places them in the issue queue. Instructions are then issued by the back-end execution core. T...
