Abstract:

A system architecture of a personal computer is modified to increase overall performance including the display of video signals while maintaining PC compatibility. A video control circuit is positioned onto a motherboard so that it directly interfaces with a local bus of a processing unit. The processing unit may include, for example, a 80386 microprocessor and a 82396 cache controller or simply a 80386 or 80486 microprocessor. As a result, the processing unit can directly read data from and write data to the video controller without always having to traverse the peripheral bus. Video data is thus transferred at the rate at which the processing unit operates and not at the slower rate of the peripheral bus.
