PURPOSE:To eliminate an influence caused by a delay of a parity check by executing a parity check instruction provided on a microprogram by other machine cycle than that of other instruction. CONSTITUTION:When executing a parity check, a data having a parity is inputted to a register A10 by an input instruction to a register A8 and an operand indication, and subsequently, a data having a parity is inputted to a register B11 by an input instruction to the register 11 and an operand indication. Thereafter, a parity check instruction is issued, and in an operand field, a parity check is indicated with regard to both the registers A10, B11, by which the parity check can be executed at the same time with regard to both registers. |
