Processor based embedded systems often need to apply simple filter functions to input data. In this paper we examine the relative energy efficiency of microprocessor and Field Programmable Gate Array (FPGA) implementations of these functions. We show that considerable savings can be achieved by adding an FPGA to a microprocessor based systems and propose a strategy to reduce the impact of the excessive leakage energy overhead in low data rate applications.
