当需要更新 DSP 业务系统的应用软件时,为了避免利用仿真器所带来的不便和硬件损坏,采用了 PCI 总线技术来取代仿真器,完成系统应用程序的更新;针对带有外围 FLASH 的 DSP 系统,设计了一整套 DSP 外围 FLASH 启动流程和应用程序的 PCI 更新方法;通过实验证明,DSP 业务系统可以通过上位机利用 PCI 总线完成 DSP 外围 FLASH 的应用程序的更新,同时在 DSP 上电启动时,也可以根据上位机的命令,选择贮存在 FLASH 中不同的应用程序加载运行.

In DSP embedded system,PCI bus technology was adopted to update the DSP system application software in stead of emulator for avoiding the inconvenience and hardware damage caused by using emulator. According to the DSP system with periphery FLASH,an overall booting flow of DSP periphery FLASH and an application program update method by PCI are designed. The experiment proved that the DSP business system can update the application program of DSP periphery FLASH through the upper computer by PCI bus. Meanwhile,different application program can be chosen to load to DSP RAM according to the host command,during DSP is booting.
