SIGNAL PROCESSING PROCESSOR AND SEMICONDUCTOR DEVICE

PROBLEM TO BE SOLVED: To provide a signal processing processor and a semiconductor device in which the increase of types or word length of data operation instructions is suppressed. SOLUTION: In the signal processing processor 100 which includes: an address register 122 for storing address data; a decoding part 110 for decoding data operation instructions; a readout processing part 140 for reading data from a memory 200 based on data operation instructions decoded by the decoding part 110 and address data stored in the address register 122; and an arithmetic processing part 150 for performing prescribed arithmetic processing to the data read from the readout processing part 140 based on the data operation instructions decoded by the decoding part 110, includes an attribute information storage part 124 for storing the attribute information of the data stored in the memory 200 corresponding to the address data in association with the address resister 122, and the readout processing part 140 controls the size of the data to be read from the memory 200 based on the attribute information.
