Patent ID: 7516259

Claim:
A system for processing video and graphics data, comprising: an arbiter having a first input, a second input, a third input and an output, the arbiter performing prioritization and arbitration between the video, graphics and processor requests, the arbiter outputting data and commands selected from the first input, the second input and the third input of the arbiter; and a combined engine having input ports, a data output and a control input for processing graphics and video data, the combined engine selectively processing either video data or graphics data in response to a signal on the control input of the combined engine, the input ports of the combined engine coupled to the output of the arbiter, wherein the combined engine includes a scaler having an input and an output for performing video scaling, filtering, and scan conversion, the input of the scaler coupled to input ports of the combined engine, and wherein the combined engine includes a color conversion unit having an input and an output for performing color conversion, the input of the color conversion unit coupled to input ports of the combined engine and to the scaler output, enabling one pass scaling and color conversion.
