Accurate dynamic power model for FPGA based implementations


Chalbi Najoua, Boubaker Mohamed and Bedoui Mohamed Hedi

This paper presents an accurate field programmable gate array (FPGA) of analytical dynamic power models for basic operators at the RTL (Register Transfer Level) level. The models are based on the frequency, the activity rate and the input precision by using the Xpower tool in the presence of the autocorrelation coefficient. The power consumed by the connection between operators was taken into account. We have validated our approach by using the FIR filter computing application in an FPGA Virtex2Pro. The experimental results show that the average accuracy of the model is higher and the maximum reached average error is equal to 10%.

Keywords: FPGA, dynamic power models, RTL level, autocorrelation.
