Energy consumption will reduce the battery life time and increase the weight and cost of mobile devices. Low-power design methods become an important issue of SOC. Until now, there is no commercial power estimates software in system-level. Users must add power estimation to SystemC simulation environment by themselves. In this paper, we proposed a system-level power estimation framework. Users can use their custom power model, and add power estimation automatically. The proposed framework separates the SystemC simulation environment and power estimation into two independent procedures. First, we generate a data collection SystemC module automatically based on the parameters set up by users. This data collection module will automatically collect the information of parameters from SystemC simulation environment, and send these information to power estimation program. Power estimation program will calculate power consumption according to these parameters and formulas set by user. Users can add power estimation to their SystemC simulation environment quickly and use our framework to analysis the power consumption of their SOC system to find improvement issues. Users can use of our framework to compare and analyze various low-power design methods. In this paper, we applied our framework to estimate the power consumption of a 3D graphics SOC to authenticate the functional and practical ability of our framework.
