PROBLEM TO BE SOLVED: To provide an arithmetic logic unit capable of performing arithmetic processing with a relatively small-scale circuit configuration in a relatively short period of time.SOLUTION: An arithmetic logic unit includes a memory device 12 which receives an input of a bit string of N (N is an integer of N≥2) bit length and stores a lookup table that is configured so as to store the data of a multiple-bit length, part of which includes a bit indicating a logical operation result between bits which are included in the input bit string, at an address indicated by the input bit string. The arithmetic logic unit accesses the memory device 12 and outputs bits which are included in the data stored in the address indicated by the received bit string. |
