双片ADSP-2106X并行数字信号处理系统在鱼雷发射机信号源中的应用

Application of Double ADSP-2106X Parallel Digital Signal Processor(DSP) System to Signal Source of Torpedo Transmitter

鱼雷发动机信号源运算量大,一般的DSP系统难以满足要求,而由双片ADSP-2106X组成的并行数字信号处理系统则可支持多DSP系统,非常适合于高速实时处理的场合。本文采用紧耦合的方式,用2片ADSP-2106X来设计发射机的信号源,详细介绍了这种高速并行数字信号处理系统的设计思路,软件编程及调试。实验证明,可编程逻辑器件的组成应用可使得该系统具有通用性强、外围器件少等优点。

The signal source of torpedo transmitter chiefly composed of double ADSP-2106X parallel digital signal processor （DSP） can operate in real time. The signal source of torpedo transmitter with double ADSP-2106X is designed by means of close coupling mode. This paper introduces the design thought of this high speed parallel DSP system, and software program and the program debugging. The experimental result shows the application of complex programmable logic device （CPLD） make the system adaptable to high speed real time field with better generality and less peripheral component.
