摘　　要：多处理器并行系统是数字信号处理器的重要发展方向之一。文中首先介绍了ADSP2106x的硬件结构和高速处理性能;然后在时域和频域中分析了滤波处理的不同情况,结合ADSP2106X的并行特点设计了滤波系统,利用芯片独特的链路口进行4片DSP互连确保处理器间的通信,同时将剩余的链路口作为数据的输出口汇总数据结果,从而避免了总线的竞争状态,使得数据的处理速度得到大幅的提高,具有广阔的应用前景。　Multi- processors parallel system is one of the most important development trends of digital signal processors. In this paper, ADSP2106x＇s architecture and high speed processing ability was introduced, then in the case of time domain and frequency domain, the result of filter was analyzed and the system of filter was designed according to the parallel characteristic based on ADSP2106X. Special link ports of four chips are interconnected to communicate among processors, while surplus link ports are regarded as the output ports of data to gather the data result, avoiding the competing status of bus. So the system greatly improves the computing speed of data and has been found wide applications in many different spheres.
