Abstract
This paper introduces the design scheme of FIR filter based on FPGA, introduces that the design technology of FIR filter based on FPGA about digital system processing arithmetic. FIR filter adopts the basic structure of direct type, the results are got by the multiplication of 1×8,then shifting and adding. Integrating advanced software of EDA to design and achieve, and giving some emulator results. This design makes high use of hardware resource about FPGA, programming with VHDL language, achieving FIR filter with high sampling level based on FPGA.
