title: [The development and applications of digital signal processing (DSP)-chip].
abstract: 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.
