摘　　要：实时识别目标在现代高科技战争中具有重要军事意义。设计了一个由5片ADSP21060组成的并行处理系统。该系统采用基于环网的数据块处理策略,主DSP将数据分割为长度相等的块,并分配给各从DSP进行处理。以FIR滤波器并行算法为例,验证了本设计在运算速度方面显著优于单DSP系统。该设计可应用到对实时性能要求苛刻的军事领域。Recognizing hostile target timely is very important in today＇s high-tech war. A parallel signal processing system with five ADSP21060 chips was designed. A ring network-based data processing mechanism was used in the system. Mater DSP partitions data into blocks with equal size and then dispatches blocks for each slave DSP. Finite impulse response （FIR） filter parallel processing algorithm was used to verify that the muhi-DSP parallel processing system has better real time performance than the single DSP system. The design of parallel processing system can be applied in military domains which have critical demand for real time performance.
