Abstract

Abstract The scalable platform architecture of the present invention includes a high bandwidth bus (32) for transmitting data at high bit rates between various video processing subsystem. A graphics processing subsystem (30), having graphics memory, is coupled to the high bandwidth bus (32). The graphics processing subsystem (30) is adapted to receive a video memory and to perform video processing when the video memory is received. The high bandwidth bus (32) is provided with expansion connectors (56, 58) for detachably coupling to various subsystems. These subsystems may include a video processing subsystem (16) and a video capture system. The high bandwidth bus is also provided with a bus bridge (34) for coupling the high bandwidth bus (32) to a low bandwidth bus (42) or a central processing unit bus.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 104 words
A video processing system comprising: substantially high bandwidth bus means (32) for transmitting data at high bit rates; graphics processing means (30) coupled to said high bandwidth bus means (32) having first graphics memory for performing graphics processing; said graphics processing means (30) having means for detachably receiving and electrically coupling to second video memory, and means for performing video processing when coupled to said second video memory; and said high bandwidth bus means (32) having a plurality of connecting means for detachably receiving a selected subsystem of a plurality of subsystems and electrically coupling said high bandwidth bus means to said selected subsystem.
Claim 2
Dependent Claim 27 words
The video processing system of claim 1, wherein first connecting means (56) of said plurality of connecting means is adapted to receive a video capture subsystem (12).
Claim 3
Dependent Claim 26 words
The video processing system of claim 2, wherein second connecting means (58) of said plurality of connecting means is adapted to receive a video acceleration subsystem.
Claim 4
Dependent Claim 22 words
The video processing system of claim 3, wherein one of said first and second connecting means (56, 58) receives said selected subsystem.
Claim 5
Dependent Claim 22 words
The video processing system of claim 4, wherein each of said first and second connecting means (56, 58) receives a respective subsystem.
Claim 6
Dependent Claim 43 words
The video processing system of claim 1, further comprising: substantially low bandwidth bus means (42); and bus bridge means (34) coupled to said high bandwidth bus (32) and said low bandwidth means (42) for selectably isolating and coupling said bus means (32, 42).
