摘　　要：自举系统在并行系统研发中占有重要地位。在分析和比较单DSP自举原理的基础上,设计并实现了一种应用在多处理器平台的混合模式自举系统。该系统采用嵌套架构结合EPROM和链路口这两种加载模式,成功实现了单Flash芯片引导多处理器间的不同应用程序。与单一模式的EPROM自举系统相比,降低开发成本、减少功耗,提高了系统的可靠性和扩展性,为多DSP的大规模集成提供了广阔的应用前景。It is important to develop boot system in the research of parallel system. After analyzing and comparing the different boot principles of single DSP, a multi-model boot system on the multi-processors is designed and implemented. The system combines two booting way of EPROM and link port in nested form, and succeeds in booting different application program of multi-processors by one flash chip. Compared with the single model boot system of EPROM, the cost and energy consuming is decreased, the system reliability and expansibility is enhanced. The novel boot way provides flexible choice for following large-scale application ofmulti-DSP.
