本文描述了一种利用美国 Am 公司新近推出的 Am29500系列芯片构成的 FFT 专用机。由于这组芯片的高度集成化、专用化和灵活的可编程性,使得 FFT 专用机的实现大为方便。而且用这组芯片实现的 FFT 专用机,按基2顺序算法,处理速度可达1024点/2ms,这样的速度是目前其它专用机所无以伦比的。文中对 Am2950系列芯片作了简单介绍,并以我们的实验为基础,介绍如何利用这组芯片实现 FFT 专用机。
This article describes an FFT dedicated machine that uses the newly introduced Am29500 series of chips from Am Corporation in the United States. Due to the high degree of integration, specialization and flexible programmability of this group of chips, the implementation of an FFT dedicated machine is greatly facilitated. And with this set of chips to achieve FFT dedicated machine, based on the order of 2 algorithms, processing speeds up to 1024 points / 2ms, this speed is currently unmatched by other dedicated machine. In this paper, Am2950 series chips made a brief introduction, and based on our experiments, how to use this chip to achieve FFT dedicated machine.
