摘　　要：针对国产异构多核微系统中DSP处理器任务的调度和启动的需求,基于可重构技术,提出了一种DSP任务动态加载方法。利用DSP处理器的HPI接口作为程序注入接口,在FPGA芯片中构建了具有总线隔离机制的配置通路,在SPARC V8处理器中以软件驱动的形式,实现了DSP任务动态加载。测试结果表明,所提出的DSP任务动态加载方法用时135 ms即可完成280 KB大小的程序注入及DSP处理器的任务加载,满足微系统的实时性需求。Based on the reconfigurable technology, a new DSP task dynamic loading method is proposed for the DSP processor in the domestic chip-level heterogeneous multi-core micro system. This method uses the HPI interface of DSP processor as the interface of the program, constructs the configuration path of the bus isolation mechanism in the FPGA chip, and implements DSP task dynamic loading. Test results show that the proposed DSP task dynamic loading method, with 135 ms completed 280 KB size of the code data injection and DSP processor task loading, meets the real-time requirement of micro system.
