1. A general purpose programmable media processor having an instruction path and a data path to digitally process a plurality of media data streams, comprising:

  • a high bandwidth external interface operable to receive a plurality of data of various sizes from an external source and communicate the received data over the data path at a rate that maintains substantially peak operation of the media processor;

    at least one register file configurable to receive and store data from the data path and to communicate the stored data to the data path; and

    a multi-precision execution unit coupled to the data path, the multi-precision execution unit configurable to dynamically partition data received from the data path to account for the elemental symbol width of the plurality of media data streams, said elemental symbol width being equal to or narrower than the data path, and programmable to operate on the data to generate a unified symbol output to the data path.
