The ever increasing complexity of the applications result in the development of power hungry processors. There is a scarcity of standalone tools that have a good trade off between estimation speed and accuracy to estimate power/energy at an earlier phase of design flow. There are very few tools that addresses the design space exploration issue based on power and energy. In this paper, we propose a virtual platform based standalone power and energy estimation tool for System-on-Programmable Chip (SoPC) embedded platforms, which is independent of in-house tools. There are two steps involved in this tool development. The first step is power model generation. For the power model development, we used functional parameters to set up generic power models for the different parts of the system. This is a onetime activity. In the second step, a simulation based virtual platform framework is developed to evaluate accurately the activities used in the related power models developed in the first step. The combination of the two steps lead to a hybrid power estimation, which gives a better trade-off between accuracy and speed. The proposed tool has several benefits: it considers the power consumption of the embedded system in its entirety and leads to accurate estimates without a costly and complex material. The proposed tool is also scalable for exploring complex embedded multi-core architectures.
