With power becoming a major constraint for multiprocessor embedded systems, it is becoming important for designers to characterize and model processor power dissipation. It is critical for these processor power models to be useable across various modeling abstractions in an Electronic System Level (ESL) design flow, to guide early design decisions. In this paper, the authors propose a unified processor power modeling methodology for the creation of power models at multiple granularity levels that can be quickly mapped to an ESL design flow. Their experimental results based on applying the proposed methodology on the OpenRISC and MIPS processors demonstrate the usefulness of having multiple power models.
