Energy-Focused Compiler-Assisted Branch Prediction

摘要

A processing system to reduce energy consumption and improve performance in a processor, controlled by compiler inserted information ahead of a selected branch instruction, to statically expose and control how the prediction should be completed and which mechanism should be used to achieve energy and performance efficiency.

1. A method wherein:
at compile time, control information is added to an instruction sequence prior to a control-flow changing instruction it controls; the control information is used at runtime to control prediction of the target address of the control-flow changing instruction.
