FIELD: information technologies.
SUBSTANCE: file register comprises multiple registers, every of which contains multiple cells of memory, at the same time the first cell from multiple cells of register memory is configured to store signal of availability, condition of which indicates whether data stored in register is valid, and other cells from multiple cells of register are configured to store data in register; and decoder configured to receive address of target register selected from multiple registers, besides decoder in response to signal of availability stored in the first cell of target register memory, selectively diverts output of data from target register, when condition of signal of availability stored in the first cell of target register memory, indicates that data in register is invalid, and makes it possible to withdraw data of target register, when condition of signal of availability stored in the first cell of target register memory, indicates that data in register is valid. Method describes operation of register file.
EFFECT: prevention of invalid reading operations.
