Title Design and Fulfillment of FIR Filter Based on FPGA
Abstract
With the great development of electronic circuit design, comparing to traditional design model, FPGA has higher flexibility and shorter development cycle which makes it one of a main circuit design models. While in mechanical engineering field, it is an extremely important question how to abstract useful signal from high disturbing signal, with noisy background. This paper makes use of Verilog HDL hardware language to functional describe design-accomplished FIR filter, with aim to utilize relatively small resources to achieve maximum operating speed. Mainly done the following work:
1. In the whole process of designing and fulfilling FIR filter, we fully studied the technique of FIR filter, the technique of IP core and the design thoughts and methods of FPGA, etc.
2. After analyzing filter design demands, the FPGA is used to finish design of each part including multiplier, IP core, etc.
3. By making simulation of the whole FIR filter’s function and testing some important characters of filter, it follow that this design has good performance and accomplishing the requirements of our design.
