摘　　要：PCI总线是先进的高性能32/64位局部总线,是应用最广泛的微机总线标准之一。讨论了以CH365作为接口芯片的PCI总线接口卡的设计方法,并给出了一个ISA总线接口卡快速改造为PCI总线接口卡的实例。在设计中使用了CH365芯片特有的本地硬件地址请求功能及双口RAM读写的仲裁技术。设计的PCI接口板实现了预定的功能,具有较强的实用性和较高的市场推广价值。The PCI local bus is an advanced and high performance 32/64 bit bus with multiplexed address and data lines, which has been become one of the most widely used bus standard. The design for interface board which used CH365 as a interface chip based on PCI Bus was discussed. The example that a interface board based on PCI bus upgrade from a interface board based on ISA Bus in short order,which is even more practicable and good for popularizing is presented. The unique local hardware address request function of CH365 chip and the technology of arbitration for reading and writing dual - port RAM are used in the this design. The intended function of the interface board based on PCI Bus designed in this paper is realized.
