PURPOSE:To provide a digital signal processor capable of detecting a part where a fault occurs and performing an operation with high efficiency. CONSTITUTION:Pass groups PVIWI, PVIVO, PVIWO, PWIVO, PWIWO, PWOWI, and PVOVI which directly deliver data to data buses DB on which a digital signal supplied via an input/output part is transferred are provided, and especially, an arithmetic part consisting of plural processors, a data flow control part, and a work memory part are arranged between the input data bus DBi and the output data bus DBo of the data DB, A tri-state buffer 16 is used in the switching selection of the bus. |
