Abstract

This paper presents a technique used to do po wer analysis of a real p rocessor at the architectural lev el. The target processor in tegrates a 16-bit DSP an d a 32-bit RISC on a single c hip. O ur po wer estimator pro vides po wer consumption data of the architecture based on the instruction/data flo w stream We demonstrat e the accuracy of the estimator by com paring the po wer valu es it p roduces against measurem en tsm adeby a gate level po wer sim ulator for th e same benc hmark set. Our estimation approac h has been shown to pro vide v ery efficient accurate pow er an alysis at the architectural level.
