FPGA hardware implementation of an RNS FIR digital filter

Efficient implementation of FIR digital filters can be achieved in the Xilinx Virtex FPGA by using residue number system (RNS) arithmetic techniques. The hardware implementation of the RNS filter can be done using lookup tables (LUT) in either the block or distributed RAM in FPGA of the Xilinx Virtex FPGA. The RAM generated by the core generator are used for this purpose. The result is a highly efficient hardware realization of the desired FIR filter.
