VHDL-FIR-filters

Synthesizable FIR filters in VHDL with a focus on optimal mapping to Xilinx DSP slices. This repository contains a transposed direct form, systolic form for single-rate FIR filters and a custom parallel polyphase FIR decimating filter. The VHDL has been synthesized with Xilinx Vivado 2015.1 to confirm the correct DSP cascade chain is inferred.
