【Abstract】 This thesis focus on mission requirements of a new generation of avionics systems,with high-speed interconnect bus in airborne embedded systems as research background,according to the development trend of RapidIO high speed interconnect technology to carry out research and design.First of all,the thesis introduces the development history and trend of avionics systems. Analyzed and contrasted several kinds of high-speed serial bus include content, technical advantages and disadvantages and application fields, based on the current development of embedded interconnect topology. Studied the RapidIO interconnect technology protocol features, communication mechanisms, configuration management and multicast affairs.Secondly,according to the above analysis and comparison, studying the implement of an airborne signal processing system interconnect communication network.Proposing an interconnect design based on high-speed serial RapidIO bus, building the system exchange network, providing communications capabilities for hardware resources such as DSP, FPGA, PowerPC processor, which connected to the RapidIO switching network. The thesis in-depth studyde of the architecture components of the system,the circuit design of each function unit and the configuration and implemention of RapidIO protocol software.Finally, the thesis analyzed the transmission mechanism of RapidIO protocol deeply, tested the actual transmission performance between devices within the system module, comparisoned and analyzed the test results and the factors affecting the transmission efficiency,and verified transmission performance of the RapidIO switching network. Test results show that the signal processing system had normal communication between nodes within the module and between modules modules, achieved the desired research goals ultimately.更多还原
