A microprocessor has an instruction decode portion, a register file, a complex operation unit, and a data storage position determining mechanism. The complex operation unit performs complex operation, including complex multiplication, using first and second complex number data supplied from the register file based on an instruction decoded by the instruction decode portion, and outputs the result of the complex operation toward the register file. Furthermore, the data storage position determining mechanism determines the storage positions of the real part and imaginary part of output data of the complex operation unit in the register file such that the storage order of the real part and imaginary part of the output data in the register file is consistent with the storage orders of the real parts and imaginary parts of the first and second complex number data. |
