摘　　要：介绍了一种基于链路口的多DSP系统的程序加载设计与实现,以及作为水声信号处理平台的实际应用。在分析ADSP-TS201S引导方式的基础上,重点介绍了DSP与FLASH之间的主机引导,以及多DSP之间链路口引导的两种引导方式。给出多DSP系统组成结构图和主机引导硬件连接图,并给出关键部分软件流程图。该引导方案采用主机引导结合链路口引导的方式完成系统程序引导,具有程序加载方便,调试修改灵活的特点。该设计在多DSP系统中具有一定的通用性,可方便地应用于其他类似多DSP系统中。The paper describes the design and the implementation of multi-DSP system procedure loading based on link port and its practical application as the underwater acoustic signal processing platform. Through the analysis of ADSP-TS201S guiding way, the paper emphasizes host machine guidance between the DSP and FLASH, and the two guidance ways between DSP and DSP link port. In the paper, multi-DSP system components and the host guiding hardware connection diagram are given, and key parts of the software flow chart are given as well. The guidance program through the combination of the host guidance with chain guide is used to complete intersection system program guidance, which has the characteristics of loading convenience, debugging and modifying flexiblility. The design scheme in multi-DSP system has generality, and can be easily applied to other similar muhi-DSP system.
