PROBLEM TO BE SOLVED: To rotate data with a simple circuit configuration. SOLUTION: In registers 23-25 inputting and holding eight-bit data of the respective rows in respective kinds of 8×8 digital data and these eight registers, digital data held in the register is shifted by a one-bit unit and one-bit data shifted-out from the respective eight registers by the shift operation are read so as to be outputted to an output bus 22 so that digital data obtained by rotating original 8×8 digital data by 90 deg. is obtained. |
