摘　　要：随着嵌入式研究的发展,在飞控计算机研究领域内,高性能嵌入式微处理器逐渐被考虑用来替代原有的X86系列微处理。而为了解决此类嵌入式微处理器与原有的采用PC/104总线标准的设备之间的通信问题,设计了一种方案,通过对AT91RM9200处理器内部总线和PC/104总线时序的分析,在Altera的FPGA芯片上,运用构建模块IP核技术,设计完成PC/104总线和ARM9总线之间的通信接口,并运用在实际的飞控计算机相关设备中,控制完成指定功能。In the flight control computer field, with the development of embedded research, the X86 - series microprocessors are being replaced by the high- powered embedded microprocessors gradually. In order to solve the comrntmication problems between thee embedded microprocessors and the devices which use. PC/104 protocol,gives a design, which analyzes the time sequence of AT91RM9200 and PC/104 bus and uses constructing module IP core technique on the FPGA chip to complete the design of the communication interface between ARM9 and PC/104 bus,which is used in the real relative devices in the flight control computer field and completes special tasks.
