基于 FPGA 的 ISA 接口设计

摘要

In the fieId of industriaI controI,the appIication of ISA bus is quite extensive.In order to simpIify the access hardware circuit of ISA bus peripheraI device,this paper adopts a design of ISA interface based on FPGA,which make the access to the peripheraI equipment more fIexibIe.%目前在工业控制领域中，ISA 总线的应用相当广泛，为了简化 ISA 总线对外围设备访问的硬件电路，采用了一种基于FPGA 的 ISA 接口设计，使得上层电路对外围设备的访问更加简单灵活。
