A cache power model and a runtime power simulation platform

Evaluating the power consumption of cache in an early time is very important for designer to judge their system whether meets the constraints of power. An improved cache power model is proposed to simulate the peak power of cache according to the system parameters. Compared with the traditional power model, it additional supports leakage power, routing power, and multi-port cache. Process scaling technology is also introduced to extend the available scope of the model. The results of experiments prove the accuracy of the power model. Basing on this power model, a runtime power simulation platform is proposed. It will help designer to research the power consumption of cache when special program is running.
