A communication controller for handling high speed multi protocol data streams, wherein a stream is comprised of frames. Communication controller has two processors, second processor initializes first processor and handles high level management and protocol functions, first processor handles the data stream transactions. First processor and second processor are coupled to two external buses. First processor handles a transaction of a frame by executing a task. First processor performs a task switch when there is a need to fetch information from an external unit, coupled to either first and second external bus, if it did process a whole frame, or if there is a need to fetch a portion of a frame from a communication channel.
