Abstract:
A direct input/output port access device which is suitable for use in a computer system and can control data access directly between an input port and an output port, the direct input/output port access device comprising:a local data bus electrically connecting the input port and the output port; an input/output port read/write controller electrically connected to the output port and the input port through an output port control/status line and an input port control/status line, respectively for controlling data accesses directly between the output port and the input port through the local data bus; and a data bus transceiver electrically connected to and controlled by the input/output port read/write controller through a data bus transceiver control line for separating the local data bus from a system data bus when data accesses between the input port and the output port is in progress.
