Method for implementing PC Card bus compatible element on application PCI bus based apparatus and circuits therefor

摘要

The present invention is a method of providing a bus switching device on an application PCI bus based apparatus for separating a command bus from data buses of a PCI bus; and providing a CPU on the application PCI bus based apparatus for controlling a switch of a line between the command bus and a PC Card bus compatible IC device, in response to a control signal sent from the CPU the bus switching device is activated for enabling the line between the command bus and the IC device so that the IC device is capable of receiving commands from the CPU and decoding the same for determining whether data sent from the data buses is required to be processed. Thus, it is possible of implementing a PC Card bus compatible element on an application PCI bus based apparatus and completely eliminating bus conflict problems.
