一、引言科学技术的迅速发展,推动了电子技术的发展,并为电子技术的应用提供了广阔的领域。实时控制系统是应用电子数字技术颇有发展前景的领域。近年来,FFT 技术的发展,开僻了电子数字技术应用的新途径。随机信息处理和实时控制,往往数据量大、实时性强,要求势字计算机有更快的运算速度、更高的可靠性。然而一般百万次级以下的通用计算机是难于胜任此任务的。为了充分发挥计算机效能,目前一般多采用通用和 I. INTRODUCTION The rapid development of science and technology has promoted the development of electronic technology and provided a vast field for the application of electronic technology. Real-time control system is the application of electronic digital technology quite promising areas. In recent years, the development of FFT technology has opened up a new way for the application of digital electronic technology. Random information processing and real-time control, often large amounts of data, real-time, potential word computer requires faster computing speed, higher reliability. However, it is difficult for a general-purpose computer below the millionth level to perform this task. In order to give full play to the effectiveness of the computer, the general use of general and more
