Abstract:
1. A method for implementing a personal computer (PC) card bus compatible element on an application peripheral component interconnect (PCI) bus based apparatus, the method comprising: providing a bus switching device on the application PCI bus based apparatus for separating a command bus from data buses of a PCI bus; and providing a central processing unit (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; prior to issuing a command, the CPU determining whether the command is either a read or write command, the CPU sending an activation signal to the bus switchman device if the command is not a read or write command; and in response to the received activation signal, activating the bus switching device for enabling a line between the command bus and the PC Card bus compatible IC device so that the PC Card bus compatible IC device is capable of receiving the command from the command bus and decoding the same for determining whether data sent from the data buses is required to be processed.
