Abstract
This paper presentes the theory and design about FIR filter in FPGA.In the article,it designs a 8 stairs lowpass digital filter.Though this example,it discusses some kinds of algorithmic of multiplier in the FIR filter,and contrasted their merits and defects.Then it finds a feasible and efficient method to design the FIR filter.
