ABSTRACT:
A vector processing unit includes a vector unit having a plurality of operation pipelines and a vector register connected to the plurality of operation pipelines, a scalar unit having a buffer, and a memory unit. A memory unit controller, which is connected between the memory unit and the vector unit and between the memory unit and the scalar unit, performs an information transfer in accordance with a serializing process among access requests by using a post instruction and a wait instruction. The access requests sandwiched between the post instruction and the wait instruction are serially carried out whereby the memory unit is serially accessed. A first unit assigns a post mark to each of access requests of vector store instructions that are issued during a time when the post instruction is being executed, and stops instruction execution of the scalar unit when there is a vector store instruction proceeding to the post instruction. A second unit detects completion of execution of an access request which proceeds to the post instruction and which does not have the post mark, and causes the scalar unit to start to operate when the above completion is detected.
