Abstract

The invention relates to a processor having a data flow unit for processing data in a plurality of steps. In one version, the data flow unit includes a plurality of consecutive stages which include logic for performing steps of the data processing, the stages being coupled together by a data path, at least one stage being coupled to a transceiver which causes data to be provided to the stage for processing or to bypass the stage unprocessed in response to a stage enable signal; a synchronizer which receives processed data from the stages and causes the processed data to be provided to external logic in synchronization with a clock signal.
