Abstract

In a pipeline data processing machine having a first unit for execution of instructions running according to a first pipeline and a second unit for storing data from a plurality of ports running according to a second pipeline, the first unit having a result register for holding results including data and address information of a flow of the first pipeline, the present invention provides an apparatus for transferring results in the result register to the second unit. A plurality of registers connected to the result register, each storing the result from at least one flow of the first pipeline and storing control information is provided. Further, a controller in communication with the second unit and the plurality of ports responsive to the control information and a flow of the second pipeline is included for selecting one of the plurality of ports in a first-in, first-out queue as a port to the second unit and for updating the control information.
