Research on the SMC interface of ARM920T and a PC/104 bus simulation

A scheme was proposed to solve the compatibility problem for standard PC/104 device applied in ARM system,based on analysis to the Advanced High-Speed Bus timing and Static Memory Controller interface model of ARM920T core processor system and IBM PC/AT and IEEE PC/104 bus specification.The difference between the ARM system and the PC plat,in the aspects of instruction set,memory model,and bus timing,etc.,was discussed in detail.The proposed method can be of great help to the design of the embedded system by taking the advantage of both ARM processor and PC/AT system.
