| Along with the computer technology and high performance computing technique development, people go in to complex, large-scale systems such as gene engineering, climate prediction, military exercise, and power systems. The original serial simulation system restricted by single processor process speed limit, serious impact on the time of system simulation and lost the purpose of the simulation. Large data processing task can be break up into many independent and parallel subtasks by parallel simulation system. Through implement and achieve these subtasks harmoniously, it achieve the simulation calculation quickly and effectively.In order to realize the real-time simulation application of embedded parallel system based on Ethernet, this paper construct a kind of double network parallel simulation system based on analysis the structure of many simulation system. The system has master-slave network structure. The host communicate with the slave used Ethernet based on TCP/IP protocol, and the slave communicate with each other used Ethernet based on MAC layer. This method both ensures the reliability of communication, and ensures the real-time parallel system.In the multi-DSP parallel system, many machines download applications process takes big long workload. In order to realize the real-time simulation application of embedded parallel system based on Ethernet, according to the analysis of the parallel simulation system structure and the basis of BF548loader file structure characteristic, this paper researches the DSP boot mode and the loading process, and proposes a kind of download method based on Ethernet’s initialization code multiple-load. This method solved the problem of DSP parallel system’s complex download procedure. Through the actual test, the feasibility and validity of the download method have been verified. It provides a convenient and flexible experiment method and realization technology of parallel simulation. |
