ABSTRACT:
A data transfer system is provided for use in shifting and transferring image data and the like, wherein the amount of shift, the horizontal size and the like of data to be shifted are held in a dedicated circuit which is connected between a CPU and a memory. A judgment is made: by a valid/invalid indication unit, based on a valid/invalid parameter or the amount of deviation between the boundary unit and the transferred data after shifting, of the validity or invalidity of the head end or the trailing end of the data after shifting. A transfer suspension control unit eliminates the transfer of the data if the data is invalid after shifting, thereby enabling the increase of the speed of transfer of image data by avoiding the transfer of meaningless data.
