PROBLEM TO BE SOLVED: To provide an arithmetic processing device which can reduce instruction codes. SOLUTION: A command memory 12 stores an instruction code as one common code which represents a plurality of common arithmetic patterns to be executed by using a plurality of logical registers. A register map table management part 14 stores a plurality of register map tables 14a, 14b and 14c which manage physical registers to be allocated to the logical registers and determines physical registers to be allocated to the logical registers by using the register map tables 14a, 14b and 14c which are designated when the common code is called out.
