PROBLEM TO BE SOLVED: To provide a semiconductor integrated circuit and a register address control device by which even when there is an addition or a revision of a function with respect to an existing semiconductor integrated circuit, software created with the existing semiconductor integrated circuit can be used, and the performance of the CPU can be improved. SOLUTION: The semiconductor integrated circuit 110 has a register map 1 to a register map N (121, 131, 141) wherein the allocations of address bits are rearranged in correspondence with a mode 1 to a mode N (120, 130 and 140). Each register map can be selected by means of the corresponding mode, and switching the mode makes one of the register maps available for use. COPYRIGHT: (C)2010,JPO&INPIT
