1. A system for unified media processing comprising:

  • a plurality of general purpose media processors, each media processor being operable at sustained peak data rates and having a dynamically partitioned execution unit, wherein a plurality of media data streams are concurrently transmitted over a single data path and are dynamically partitioned according to an elemental symbol width that is equal to or narrower than the data path, and having a high bandwidth interface, the high bandwidth interface coupled to external memory and input/output elements to receive and transmit data to the media processor at substantially peak rates; and

    a bi-directional communication fabric, the plurality of media processors coupled to the bi-directional communication fabric to transmit and receive at least one media stream comprising presentation, transmission, and storage media information; and

    wherein each media processor further comprises dedicated memory and wherein the each of the plurality of media processors can employ any unused portion of the dedicated memory of another media processor in a shared manner to efficiently store and retrieve presentation, transmission and storage media information at substantially peak data rates.
