Abstract
Power is increasingly becoming a design constraint for embedded systems. A processor is responsible for energy consumption on account of the software component of the embedded system. The power estimation of this component is a major concern due to the rising complexities of processors and the slow estimation tools. This work attempts to estimate the energy dissipation of the PR1900/sup 1/ processor based on instruction set model with improved accuracy. The model is integrated in a simulation framework and validated. Over 200 times speedup has been obtained with average 1.4% loss in accuracy over gate level estimation. Analysis of the energy dissipated by the instruction vis a vis the processor architecture has been carried out and a substantial reduction in the measurement effort to build the processor energy model has been achieved.
