<P>PROBLEM TO BE SOLVED: To enhance operation performance while suppressing an increase in the number of read paths from a register. <P>SOLUTION: A computing unit 11 can receive an input of either of read-out data from a register and an immediate value as each of two operands. A computing unit 12 can receive an input of either of read-out data from a register and an immediate value as one operand and receives only an immediate value as the other operand of two operands. A control part 13 determines whether each of the two operands in the operation relative to an input operation execution instruction is the read-out data from the register or the immediate value, based on the input operation execution instruction, and makes any of the computing units 11, 12 execute the operation relative to the input operation execution instruction. <P>COPYRIGHT: (C)2012,JPO&INPIT |
