PURPOSE:To improve the design efficiency and to process debug simply in a short time, by assigning the same conventional register to a register on a program where the range of operating address of a virtual register is not duplicated in time. CONSTITUTION:An address of a virtual register is stored to a reference register RG-A, register information and the operating address from an original program are stored in a register RG-B, and the register information is compared CMP1. When the result is coincident or finished, each address is stored on an address operating range storage list TBL. An operating end address Rj and an operating start address Ri of the next register are compared CMP2 as to a virtual register, and when Ri>Rj, the conventional register of the same number is designated and written to both the virtual registers with a write processing section WRP. When Ri<=Rj, they are compared CMP3 further. When the assignment on the list TSL to real registers is finished, a program SM is outputted. |
