ABSTRACT:
A data processor has a plurality of vector registers capable of reading and writing in parallel; a plurality of ALU's; a plurality of sending circuits, one for each of said vector registers, each for updating a read address for the corresponding vector register requested by a succeeding instruction within such a limit that said read address does not pass a write address for said corresponding vector register requested by a preceding instruction and sending out a read data together with a data valid signal for each updating; circuits for sending the data and the data valid signals from said plurality of sending circuits to the ALU's requested by the corresponding instructions; and circuits, one for each of said ALU's, each for controlling the corresponding ALU such that when the data valid signals have been received from all of the vector registers necessary to execute the instruction which uses the corresponding ALU, the corresponding ALU operates on the data supplied with said data valid signals and sends out a data valid signal.
