Design And Implementation Of PCI-to-ISA Card

This paper mainly studies the design manner and its realization of PCI-to-ISA conversion. At first, PCI bus protocol and electrical specification are analyzed in this paper, data transfer and the function of PCI bus configuration space and its structure are also discussed. The paper has put forward the developing methond based on PCI bus.Then, a PCI interface design proposal and implementation using PCI9052 is represented detailedly from the view of hardware designing and driver developing. Consequently, the extendable microcomputer local bus has been formed according to design requirements. In driver development part, features of WDM and DriverWroks are introduced, especially programming of PCI-to-ISA card driver.At present, the PCI-to-ISA card has beening successfully used in the syetem for microcomputer interface technology experiment, fully satisfies the need.
