Abstract

PURPOSE:To make high in check speed, by setting right or left data by shift amount, setting them left or right and checking if the shift-out data is zero. CONSTITUTION:A shift amount is set to a shift control 38, the content of an A register 31 is shifted right by the shift amount and returned to a B register 32. Next, the content of the B register 32 is stored in a designated part, the content of the A register 31 is shifted left by the shift amount and stored in the B register 32 to check if the content of the B register 32 is zero. In case of a shifter bit 23 with shift right 24-bit for the shift amount, when an AND gate 36a is smaller than a bit 23, the shift right signal 1 is inputted to indicate the shift right, and when an AND gate 36b is greater than a bit 24, a shift left signal is inputted to indicate shift left, allowing to transmit the shift right to an output bus 37, when a shifter bit 23 is inputted.
