Implementation of High-speed and High-tap FIR Filter Based on Distributed Arithmetic and FPGA

In the digital signal processing,the high-tap FIR filter with special DSP chip works slowly.In order to solve the mentioned problemt,his paper introduces a new method to implement high-speed and high-tap filter based on distributed arithmetic(DA) and field programmable gate array(FPGA).As an illustrative instance,16-tap finite impulse response(FIR) filter is designed with the Xilinx Corporation’s xc2v500 chip in detail.The experimental results suggest the system is reasonable and reliable and can satisfy the design requirements by simulation and synthesis.
