This paper presents generation tool and performance results on a method to minimize the amount of hardware needed to implement a parallel digital finite impulse response (FIR) filters for hardwired (fixed coefficients) implementation targeted for high performance. The generation tool employ a combination of two approaches: first, the reduction of the coefficients to NPower- of-Two (NPT) terms, where the maximum number of non-zero in each coefficient is taken as a constraint, followed by Common Subexpression Elimination (CSE) among multipliers. Synthesis results for a range of different filter specifications, using Quartus II FPGA synthesis tool are presented.
