基于PC104多DSP并行处理系统

Multiple DSP parallel processing system based on the standard PC/104 bus

针对嵌入式组合导航系统,研制了一种基于PC104总线的嵌入式多DSP并行处理系统。该系统采用PC／104 CPU模块作为控制系统,三路独立的DSP处理模块组成数据处理模块,PC／104主机与F206DSP的数据交换是通过共享存储器完成的,系统接口译码则由CPLD器件完成。本文还就该系统的数据交换、中断通信和CMD文件软件设计进行了介绍。

In order to apply embedded data processing to integrated navigation. The principal-subordinate distributed multiple DSP parallel processing system based on the standard PC/104 bus is researched. The embedded computer with the PC/104 CPU is used as a control system, three individual DSP process modules constitute the data process part, the PC/104 host exchange data with the F206 DSP chip by sharing memory, and the CPLD chip takes charge of the system's interface coding in the parallel processing system. The software design of the data exchange, interrupt communication and the CMD file design in the system are introduced in this paper.
