ABSTRACT:
The "chip set" of a graphics adapter interface card is reduced to a monolithic integrated circuit that includes a programmable analog clock circuit for producing a video memory clock and a video dot clock. A digital graphics adapter controller is responsive to the video memory clock and the video dot clock to produce a video information stream. A random-access memory is responsive to the video information stream to produce a video display information stream, and a digital-to-analog converter is responsive to the video display information stream to convert the video display information stream to analog signals for application to a video display device.
