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。
Digital signal processing (DSP) system due to the speed limit, its real-time in a considerable amount of time is far less analog signal processing system. From the 1980s till now, DSP chips have made epoch-making development in terms of computing speed, computing precision, manufacturing process, chip cost, size, operating voltage, weight and power consumption, and the development tools and means have been continuously improved. DSP chip has a very fast computing speed, so that many DSP-based real-time digital signal processing system to be achieved. At present, DSP chip has been used in communications, automation, aerospace and medical fields, and achieved considerable results. In the field of manned space flight, DSP chip-based technology has broad application prospects.
