摘　　要：数字信号处理（ＤＳＰ）系统由于受运算速度的限制，其实时性在相当的时间内远不如模拟信号处理系统。从８０年代至今的十多年中，ＤＳＰ芯片在运算速度、运算精度、制造工艺、芯片成本、体积、工作电压、重量和功耗方面取得了划时代的发展，开发工具和手段不断完善。ＤＳＰ芯片有着非常快的运算速度，使许多基于ＤＳＰ芯片的实时数字信号处理系统得以实现。目前，ＤＳＰ芯片已应用在通信、自动控制、航天航空及医疗领域，取得了相当的成果。在载人航天领域，基于ＤＳＰ芯片的技术具有广阔的应用前景。Due to the limitation of operation speed, real time performance of digital signal processing (DSP) system is far from that of analog signal processing system in decades ago. Since early 80's, DSP chips have been greatly improved in the following aspects: operation speed, computation precision, fabrication technics, cost, chip volume, operational power supply voltage, weight and power consumption. Furthermore, development tools and methods have been developed greatly. Modern DSP chips can be operated very fast, which make the implementation of many DSP based signal processing system possible. Now DSP chips have been widely applied successfully in communication, automatic control, aerospace and medicine. DSP based technology has very promising future in manned space flight area.
