PROBLEM TO BE SOLVED: To realize the integration of functions performing similar processing and to economize a required memory capacity. SOLUTION: In a register file (REGS) 7, R1 stores the memory address of a transfer source, and a SVAL stores prescribed information. A special address register (SADDR) 9 stores a specific memory address. A comparator (CMP) 11 compares the transfer source memory address with the specific memory address. As a result, if the transfer source memory address coincides with the specific memory address, the prescribed information stored in the SVAL is read instead of information stored in a corresponding area of a memory 2 shown by the transfer source memory address stored in the R1 of the file (REGS) 7.
