Design and FPGA Implementation of High-speed Parallel FIR Filters

Abstract

This paper proposes a novel design method of parallel Finite Impulse Response (FIR) filter, which structure is parallel transposed. It can increase the running speed by M times compared with the serial FIR filter, where the M is the number of sub-filters, and the parallel FIR filter only introduces very small delay. Firstly the theoretical foundation of parallel FIR filters is analyzed.
