Architectural level throughput based power modeling methodology and apparatus for pervasively clock-gated processor cores

摘要

A method, system, and apparatus for estimating the power dissipated by a processor core processing a workload, where the method includes analyzing a reference test case to generate a reference workload characteristic. Analyzing an actual workload to generate an actual workload characteristic. Performing a power analysis for the reference test case to establish a reference power dissipation value. Estimating an actual workload power dissipation value responsive to the actual and reference workload characteristics and the reference power dissipation value
