Implementation of FIR Filter Based on Distributed Arithmetic and FPGA

In the digital signal processing,the FIR filter with special DSP chip works slowly.In order to solve the mentioned problem,introduces a new method to implement 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 ProASIC3 A3P250 chip from ACTEL Corporation in details.The experimental results suggest the system is reasonable and reliable and can satisfy the design requirements by simulation and synthesis.
