一种基于IP Core实现FFT变换的新方法

A new method to realize FFT based on IP core

在数字信号处理领域,传统的快速傅里叶变换(FFT)实现方法无非通过软件编程和ASIC这两种方法来实现,而FPGA的出现使人们在实现FFT又多了一个方便快捷的选择。本文提出了一种基于Altera公司的FFT IPCore实现FFT的方法,该方法简单、灵活,可以缩短工程开发周期,节约成本。

In digital signal processing field, the traditional FFT is often realized by software and ASIC. Now, due to the emergence of FPGA, FFr can be realized by more convenient and flexible methbods. A novel approach to compete FFr is represented on the basis of FPT IP Core developed by Altera. It has many advantages such as simplicity, flexibilifies, short periodicity and low cost.
