PROBLEM TO BE SOLVED: To provide an SIMD (Single Instruction-stream, Multiple Data-stream) type microprocessor performing data communication with an adjacent processor element, which performs proper forwarding control, and to provide an operation method. SOLUTION: A PE (Processor element) 3 of the SIMD type microprocessor 1 includes a path for forwarding data of an A register even between adjacent PEs in addition to a path for forwarding data of an A register 3h in its own PE, and a third PE shift 3e for selecting the paths with control from a GP (Global Processor) part 2, and a control circuit in an SCU of the GP part 2 makes the third PE shift 3e select the forwarding path in accordance with a distance between a write destination PE of the preceding instruction and a read destination PE of a subsequent instruction.
