There is provided an SIMD processor array system in which data can be efficiently transferred between processor elements located at different distances. The SIMD processor array system includes a control processor (CP) that is capable of issuing a plurality of instructions at the same time, and a PE array that includes a plurality of mutually-connected processing elements (PEs) to be controlled by the CP. The CP issues an inter-PE data shift instruction to each PE. According to the inter-PE data shift instruction, each PE performs a data sending operation of copying all the contents of a transfer data storing part of an adjoining PE to a transfer data storing part (MBF) of the own PE, and a data fetch operation of copying part or all of the contents of the MBF of the adjoining PE to a transfer data fetch and storing part (RBUF) of the own PE if part of the contents the MBF of the adjoining PE coincide with the contents of an ID storing part (IDB) of the own PE.
