对于现今的电子系统而言,尤其是图像处理、视频通讯等系统在处理信号方面有很高的要求,信号上要满足灵活性以及实时性,同时目前的信号处理器无法满足灵活性以及实时性方面的需求。随着EDA以及可编程逻辑器件相关技术的不断发展,无论是从成本、灵活性性能以及功耗等方面出发,FPGA都体现出了很大的优势,在信号处理领域中已经广泛运用到了基于FPGA的信号处理器。本文主要实现了基于FPGA的IIR数字滤波器。
For today’s electronic systems, especially in systems such as image processing and video communication, there are high demands in signal processing. The signals must meet the requirements of flexibility and real-time performance, and the current signal processors can not meet the requirements of flexibility and real-time performance The demand. With the continuous development of EDA and related technologies of programmable logic devices, no matter from the aspects of cost, flexibility performance and power consumption, etc., FPGAs have shown great advantages. In the field of signal processing, FPGA Signal processor. This article mainly implements IIR digital filter based on FPGA.
