基于HPI互连的双DSP高速信息处理系统的设计

Design of Dual DSP High-speed Information Processing System Based on HPI Interconnection

单片数字信号处理器(Digital Signal Processor,DSP)的处理能力无法满足某飞行控制系统的需求。为此采用两片浮点DSP处理器TMS320C6713B构成高速并行信息处理系统。为实现双DSP之间的高速通信,系统利用DSP集成的HPI模块进行双DSP的互连。介绍了系统的整体框架及软件设计,并对基于HPI互连的关键技术加以详细说明。实践证明此系统通信速率高、处理速度快、系统体积小、功耗低。

The processing of signal DSP can not fill with the demand of the flight control system,therefore two chips of TMS320C6713B are used to design the high-speed information processing parallel system.In order to implement the high-speed communication between the dual DSP,they are interconnected in the system by the HPI module that integrated in the DSP.The system＇s whole architecture and the software design,key technologies about HPI interconnection are presented particularly.It is proved that the system has a high communication rate,rapid processing speed,small volume and low power consumption.
