Abstract
Abstract Scalable platform architecture includes a high bandwidth bus for transmitting data at high bit rates between various video processing subsystems. A graphics processing subsystem, having graphics memory, is coupled to the high bandwidth bus. The graphics processing subsystem is adapted to receive a video memory and to perform video processing when the video memory is received. The high bandwidth bus is provided with expansion connectors for detachably coupling to various subsystems. These subsystems may include a video processing subsystem and a video capture system. The high bandwidth bus is also provided with a bus bridge for coupling the high bandwidth bus to a low bandwidth bus or a central processing unit bus.
