摘　　要：本文给出一种由PC／AT和TMS320C25DSP组成的主从式数字处理系统，介绍了其在声呐设备检查测试中的几个典型应用．A main-slave digital processing system is presented. It is composed of a universal micro-computer PC/AT and muIti-chip TMS320C25 digital signal processors, while a dualport memory is used for inter data communication. Some fundamental applications such as the measurement of the amplitude and phase uniformity for multple pre-processing channels,the measurement of the multi-beam forming on water tank, the testing of sensors, and display of waveform, are described.
