High Performance IIR Filter FPGA Implementation Utilizing SOS Microcode Core
Ondřej Zoubek, Tomáš Musil · Transactions on Electrical Engineering · 2019
This paper discusses the methods of optimal IIR filter FPGA implementation. The methods are focused on the reduction of occupied resources and increasing data throughput. Higher demands on an internal controller complexity are successfully solved by utilizing programmable microcode controller. The novelty of SOS core and its capabilities are presented and different variants of SOS core are assessed. The workflow of IIR filter design using MATLAB considering rounded coefficient method is demonstrated.
