Abstract

The power aware design of microprocessors is becoming increasingly important. Power aware design can best be achieved by considering the impact of architectural choices on power early in the design process. A natural solution is to build a power estimator into the cycle simulators that are used to gauge the effect of architectural choices on performance. Cycle simulators intentionally omit considerable implementation detail in order to be efficient. The challenge, is to select the details that must be put back in if the simulator is required to also produce meaningful power figures. In this paper we propose how to augment a cycle simulator to produce these power figures.
