摘　　要：通过对 TMS32 0 C31自引导方式及其缺陷的研究与分析 ,针对一种基于 PC总线的 TMS32 0 C31通用信号处理系统提出了程序动态二次加载方法 ,克服了传统加载方法中算法程序大小受 DSP系统与主机共享存储器容量的限制 ,实现了 DSP系统通过主机对大型程序的加载 ,增强了系统的灵活性 ,使得同一硬件环境能够动态配置不同的 DSP软件 。Through the research and analyzing on the boot-loading mode of TMS320C31 and it's limitation, we present a new method of dynamic double boot loading used for host/DSP system based on PC bus, which conquers the limitation of the program to be loaded must be less than the memory space shared with host computer in typical boot loading. The method realizes boot loading large-scale program into DSP system and make the system more flexible. With the double boot-loading method the system can load different large-scale software dynamically in the same hardware to implement distinct functions.
