Abstract:
1. A system for processing video and graphics data, the device 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; a combined engine having input ports, a data output and a control input for processing graphics and video data, the combined engine 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 arbiter includes a parser having an input and output for receiving command words, performing arbitration, and providing instructions, the input of the parser coupled to receive commands, and the output of the parser coupled to the control input of the combined engine; and a processor and a multiplexer, the processor having an output coupled to a first input of the multiplexer, and wherein the output of the parser is coupled to an second input of the multiplexer, the output of the multiplexer coupled to the input ports of the combined engine, the multiplexer selecting between providing data from the CPU and data from the parser as input to the combined engine.
