There is provided a vector processor based on a pipeline control method in which a cyclic operation is divided into a plurality of stages and processed. This processor comprises a vector register controller for dividing an operating process into a plurality of fundamental process units and controlling these units, and a phase generator for allowing the vector register controller to time-sharingly make the vector processor operative. This vector processor reads out data from vector registers in which vector elements are stored, operates this data and writes the result of operation into the vector register. With this vector processor, a cyclic operation can be processed in parallel at a high speed without causing a remarkable increase in hardware.
