ABSTRACT:
A video peripheral board for providing video I/O capabilities to a general purpose host computer. The video peripheral board comprises a video I/O port configured to connect a video device, a bus interface circuit, and a processor. The bus interface circuit is configured to connect the video peripheral board into a system bus of the host computer, and is capable of becoming bus master of the system bus. The bus interface circuit includes a bus master address generator, a data buffer and bus control logic that provides and receives bus control signals to and from the system bus to effect read and write operations over the system bus independent of the central processing unit of the host computer. The processor controls the bus interface circuit and the video I/O port to effect transfer of video data between the video I/O port and storage of the host computer, the video data passing through the video I/O port in real time.
