A practical power model of AMBA system for high-level power analysis

摘要

Nowadays, the communication architecture has become a major source of power consumption in complicated System-on-Chip (SoC) designs. In this paper, a practical cycle-accurate power model for on-chip communication architecture using AMBA system is proposed to help high-level power analysis. According to the distinct properties of each bus component, different methods are adopted to build accurate power models. In addition, the proposed power model can be integrated into RTL simulator easily, which allows performing the power analysis at high level. The experiment results have shown that the average error of the proposed power model is less than 5.14% and the simulation overhead is less than 8.7%.
