decoupled access-execute: Pioneering compilation for energy-efficiency
Energy efficiency is essential among others for performance, to prevent thermal hazards, and to enable more simultaneously-active cores.
This talk presents software decoupled access-execute (DAE), a compilation technique we pioneered for improving energy efficiency. The compiler decouples the code into coarse-grain memory-bound and compute-bound phases, to re-enable hardware capabilities for energy management and to enhance memory- and instruction-level-parallelism.
