实时快速傅里叶变换系统的设计

Design of Real time Fast Fourier Transform System

采用专用快速傅里叶变换集成芯片是完成实时数字信号处理的重要手段之一。该文介绍了美国Ｒａｙｔｈｅｏｎ公司的ＴＭＣ２３１０芯片的工作原理，提出了公用存贮器的使用管理方法，并从工程实际出发，就ＴＭＣ２３１０芯片、ＰＣ机接口技术，采用ＩＳＡ系统总线对整个信号处理系统的设计思路作了介绍，给出了标准信号的处理分析结果。经科研实验，证明该系统具有可靠性高、速度快等优点。

Using the FFT IC for the completion of the real time numerical signal is one of the most important means In this paper, the working principle TMC2310 made by American Raytheon is introduced and the method for using and running the general purpose type of the store is suggested. Taking into account of the engineering practice, technique of the joints for the PC working around the core. TMC2310, the design of all the signal process system,using the generating system ISA are introduced. In the addition to the above, with the purpose of the experiments of the scientific research, the results of the normalized signal process analysis are given. It has been proved in the practice that the system has many advantages, such as great reliability, high operation speed and so on.
