摘　　要：多信号处理板多处理器系统已经广泛应用于高速信号处理领域。多处理器的结构和子板间的数据传输速度是系统设计的难点。本文具体介绍一种双总线的高速信号处理多子板结构系统。基于VME总线的高可靠性以及FPDP总线的高速传输能力,系统采用VME总线完成板间程序下载,采用FPDP总线完成板间数据传输。并且提出一主三从的多处理器结构,增强了系统的重组性和扩展性。文中详细讨论了该系统中多DSP通用并行处理机的硬件设计,并就系统结构和供电方案给出原理框图。In the field of high-speed signal processing, the multi-boards system composed of signal collection and signal processing can achieve goals. The configuration of multi-processors and the speed of data transfer are intractable problems. A kind of multi-boards high-speed processing system based on double bus is introduced. In the system, due to its characteristics of high reliability, VME bus is used to download program; FPDP bus is used in data transfer because of high-speed characteristic. And the design composed of one master with three slave processors is applied for enhancing expansibility of the system. Principle diagram of multi-DSP parallel processing board and power supply are also given.
