Integrated multimedia system
First Claim
1. An integrated multimedia system having a multimedia processor disposed in an integrated circuit, said system comprising:
- a first host processor system coupled to said multimedia processor;
a second local processor disposed within said multimedia processor for controlling the operation of said multimedia processor;
a data transfer switch disposed within said multimedia processor and coupled to said second processor for transferring data to various modules of said multimedia processor, at least one of which is a data cache, wherein said data transfer switch is configured to transfer data in either direction between said data cache and a module within said multimedia processor as requested by said modules;
a data streamer coupled to said data transfer switch, and configured to schedule simultaneous data transfers among the various modules disposed within said multimedia processor, in accordance with corresponding channel allocations;
an interface unit coupled to said data streamer having a plurality of input/output (I/O) device driver units;
a multiplexer coupled to said interface unit for providing access between a selected number of said I/O device driver units to external I/O devices via output pins, said I/O device driver units are provided to the interface unit directly connected to the multiplexer; and

Abstract
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.
