Abstract
An integrated multimedia system has a multimedia processor disposed in an integrated circuit. The system comprises a first host processor system which is coupled to the multimedia processor. A second local processor is disposed within the multimedia processor which controls the operation of the multimedia processor. A data transfer switch is disposed within the multimedia processor and coupled to the second processor which transfers data to various modules of the multimedia processor. A fixed function unit is disposed within the multimedia processor, coupled to the second processor and the data transfer switch and configured to perform three dimensional graphic operations.A data streamer is coupled to the data transfer switch, and configured to schedule simultaneous data transfers among a plurality of modules disposed within the multimedia processor in accordance with the corresponding channel allocations. An interface unit is coupled to the data streamer and has a plurality of input/output (I/O) device driver units. A multiplexer is coupled to the interface unit and provides access between a selected number of I/O device driver units and external I/O devices via output pins. A plu…
