RECONFIGURABLE PROCESSING SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide reinforced flexibility to the improvement of the expansion method and device acting like decoding and/or expanding plural different coded input signals. SOLUTION: A multiple standard video decoder is provided with plural processing stages 36 arranged as pipeline processing units interconnected by a 2-wire interface. A control token and a data token are sent via 2-wire interfaces 31, 42 to send both control signal and data in a token format. A token decoding circuit 33 is placed on a specific stage to recognize a specific tone as a control token specific to the specific stage and to send a control token not recognized along with a pipeline. A reconstruction processing circuit reconstructs the selected stage and processes recognized and discriminated data token in response to the recognized control token placed on the selected stage.
