Dynamic window mechanism for preventing invalid information propagation from the PCI bus

Image Number 18 for United States Patent #5983300.

A method and apparatus to prevent invalid data from propagating into devices connected to a PCI tristate bus is provided. The method and apparatus utilize the PCI bus control signals to monitor the bus transaction's mode (e.g., as a bus target or as a bus master), type (e.g., read, write), and status (e.g., ongoing bus transaction). Using these information, control the opening and closing of a window gate hardware to allow valid data to propagate into a device connected to the PCI tristate bus and to prevent invalid data from propagating into the device.
