Abstract :
Because of the increasing importance of cross coupled capacitances in deep submicron technologies, it is of great interest to extend the existing high-level power estimation techniques by considering the spatial correlation between adjacent lines. This work addresses the modeling and estimation of power dissipation in on-chip buses based on the statistical properties of data sequences. Using the derived models, a power estimation technique is proposed and evaluated for various coding schemes. For different DSP applications, our results depict less than 5% discrepancy with precise bit level estimations
