ABSTRACT:
The present invention provides an integrated display system for multi-media workstations wherein graphics image and video data are merged in a single frame buffer. The integrated display system employs 3-port VRAMs with a first serial access port for display data output, and a random access port for graphics data, a second serial access for video data input. The display system includes a single frame buffer memory system for a multi-media workstation which operates compatibly with display systems and logic designed for dual frame buffer systems and it uses the 3-port VRAM in combination with a means incorporating improved input locking, video update or refresh, and encoded video data input stream.
