PROBLEM TO BE SOLVED: To provide a register file which efficiently accesses to a register by register indirect designation. SOLUTION: At the time of register writing by register indirect designation, a selector 1112 selects data which a selector 1111 selects and a register in a data storage part 114 holds. A writing signal generation part 1113 generates a writing signal based on selected data. At the time of register reading, a selector 1122 selects data which a selector 1121 selects and a register in the data storage part 114 holds. A selector 113 selects and outputs one of data which the register in the data storage part 114 outputs based on selected data.
