An integrated multimedia system having a multimedia processor is disposed in an integrated circuit having a first host processor system coupled to the multimedia processor and a second local processor disposed within the multimedia processor for controlling the operation of the multimedia processor. A data transfer switch is coupled to the second processor for transferring data to various modules of the processor, at least one of which is a data cache. The data transfer switch transfers data in either direction between the cache and a module within the processor. A data streamer schedules simultaneous data transfers among the various-modules disposed within the multimedia processor in accordance with 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 plurality of external I/O devices are coupled to the plurality of I/O device driver units via a multiplexer.

Integrated multimedia system

An integrated multimedia system has a multimedia processor disposed in an integrated circuit. A 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 processor which transfers data to various modules of the multimedia processor. A fixed function unit is disposed within the multimedia processor, coupled to the processor and the data transfer switch. 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. As interface unit is coupled to the data streamer and has a plurality of I/O device driver units. A multiplexer coupled to the interface unit provides access between a selected number of I/O device driver units and external I/O devices via output pins.

Integrated multimedia system with local processor, data transfer switch, processing modules, fixed functional unit, data streamer, interface unit and multiplexer, all integrated on multimedia processor
