摘　　要：为了实现基于以太网的嵌入式并行系统的实时仿真应用,在分析并行仿真系统结构的基础上,根据BF548装载文件结构的特点,研究了DSP的启动方式和任务程序加载过程,提出一种基于以太网的初始化代码多重加载的下载方法。该方法可实现DSP启动后自动下载任务程序,解决了多DSP并行系统任务下载过程复杂繁琐的问题。通过实际测试,验证了该下载方法的实用性、可行性和有效性,为并行仿真应用提供了一种方便、灵活的实验手段和实现技术。In order to achieve the real - time simulation application of embedded parallel system based on Ethernet, the DSP boot mode and the loading process are researched according to the analysis of the parallel simulation system structure and the basic characteristic of BF548 loader file structure. This paper also proposes a kind of download method based on Ethernet＇s initialization code multiple - load. This method can realize task program automatic download after DSP launched and solve the problem of complex download procedure of DSP parallel system. Through the actual test, the feasibility and validity of the download method have been verified, which provide a convenient and flexible experimental method and implementation technique of parallel simulation.
