Different FPGA Implementations of Audio Processing Using Least Mean Square Adaptive Filtering: A Comparative Study

Abstract

This paper proposes audio signal processing implementation on two different multimedia FPGA board (Zybo and Zed Board). The audio signal coming from audio codec is adaptive filtering using LMS algorithm and it is implemented on FPGA. The comparative study has been done in terms of hardware resource utilization, static and dynamic power dissipation and speed of the system. The interesting result we have found is that hardware resource utilization and delay are less in ZYBO as compare to Zed multimedia board and also, we have found that the static power dissipation is less and dynamic power dissipation is more in ZYBO multimedia board.
