Design and implementation of interface system of simulator based on ARM technology

In order to improve the technology of the simulator input& output interface system based on serial communication bus in a low communication rate,the distribution of the limited distance and difficult to debug,a distributed intelligent input & output interface system based on the ARM and Ethernet technology is proposed.The design and implementation of a intelligent input& output interface system based on embedded microprocessor chip ARM and Ethernet technology is introduced,including the system design,the hardware realization,definition of the table of the configuration and I/O management & communication software,etc.The hardware and software of this I/O interface system is debugged and run,and the result indicates that this I/O interface system have a high data transfer rate,a big range of the distributing,and also can easily expand,this I/O interface system meets the design and application requirement of simulation system.
