摘　　要：用ＡＤＳＰ２１０２０ 浮点数字信号处理器实现声纳数字信号处理机，使传统的声纳数字信号处理机大为简化，仅用３ 片ＡＤＳＰ２１０２ 芯片，再配上外围电路，即可实现对４８ 波束、３２ｋＨｚ 采样速率的输入信号进行处理，并输出至后置分机或显示控制台。研究结果表明，ＡＤＳＰ２１０ＸＸ系列ＤＳＰ芯片特别适合于多路数字信号处理。The implementation on sonar real time signal processing machine based on ADSP21020 greatly simplifies the complexity of the traditional sonar signal processing machine and improves the reliability of the sonar system. Using only three pieces of ADSP21020 and some peripheral circuits, 48 channels 32 kHz input digital signal can be processed, and the processing results to the latter units and the display control console can be sent. The result shows that the ADSP210XX series DSP is especially suitable for multi channels digital signal processing.
