This work proposes an VHDL generation software for optimized FIR filters. In this paper a near optimum algorithm for constant coefficient FIR filters was used. This algorithm uses general coefficient representation for the optimal sharing of partial products in Multiple Constants Multiplications (MCM). The developed tool was compared to Matlab FDA toolbox. Synthesis results show that our tool is able to produce significantly better hardware than FDA toolbox, doubling the speed and reducing the silicon area by 75%. The software produces a generic VHDL output, synthesizable to ASIC or FPGA.
