摘　　要：介绍了一种基于ADI公司的双片ADSP-TS201S型DSP芯片的数字信号处理器并行工作模式的设计。采用EPROM加载和链路口加载的方式分别对主片和从片进行程序的引导加载。简单介绍两片DSP的分工工作模式:其中主片DSP可以用于与外部进行数据交互通信和对双片DSP的控制管理;从片DSP可以专用于整个系统核心算法的实现。两片DSP通过DMA中断进行算法的同步以保证整个系统的实时运转。大致介绍系统构成,远程管控的实现方式。详细介绍主片的远程参数数据库和核心算法程序的更新所采用的设计方法。主片接收外部传递的信息及数据采用中断模式进行。A design of parallel working of digital signal processor which is based on dual -chip ADSP -TS201S is presen- ted in this paper. Processor booting methods of dual -chip ADSP- TS201S are different, the master chip booting the pro- cessor from EPROM and slave chip booting the processor from link port. Working mode of dual - chip ADSP - TS201S are briefly introduced, master chip applies for data communication with external apparatus and dual - chip controlling manage- ments, primary arithmetic of whole system is carried out on slave chip. The synchronization of arithmetic on dual - chip is a- chieved through DMA complete interrupts. In this paper, the structure and realization of remote control of the system are simply described, design of parameter database and core arithmetic remote updating on master chip is particular given. The data traffic between master chip DSP and external apparatus is achieved through DMA interrupts.
