PROBLEM TO BE SOLVED: To achieve a high speed arithmetic operation by reducing access quantity to an external memory, and efficiently performing the data transfer of processing data even in the case of signal processing when it is necessary to perform the high speed arithmetic operation of data whose capacity is large. SOLUTION: This multiprocessor signal processor is provided with a first processor 2, a second processor 4, a third processor 6, a first local shared memory 8 as a memory connected to an external bus 12, and shared by the first processor 2 and the second processor 4; and a second local shared memory 10 as a memory connected to the external bus 12, and shared by the second processor 4 and the third processor 6, wherein the first local shared memory 8 is provided with a first bank 8A, a second bank 8B, and a third bank 8C, and the second local shared memory 10 is provided with a first bank 10A and a second bank 10B and a third bank 10C.
