当前ＦＦＴ（ＦａｓｔＦｏｕｒｉｅｒＴｒａｎｓｆｏｒｍｓ）可以利用ＤＳＰｓ或微处理器以软件方式实现，也可用专用器件及通用的ＶＬＳＩ来获得高效能的ＦＦＴ。对于后者，主要的问题是资金开销、设计风险以及设计时间。本文介绍了用可编程逻辑器件自动实现ＦＦＴ处理器的设计工具，并介绍其设计方法与应用。 The current FFT (FastFourierTransforms) can be implemented in software using DSPs or microprocessors, as well as specialized devices and general-purpose VLSI for efficient FFTs. For the latter, the main issues are funding costs, design risks and design time. This article describes the design of programmable logic devices automatically FFT processor design tools, and describes its design methods and applications.
