Abstract

PURPOSE:To rotate and move a data witout using other data save area than a data store area of a storage means, by exchanging the data through at least 2 registers. CONSTITUTION:In the first process, through the registers 5 and 6, replacement of a data DN-M+1 of an address 1 and a data DN of an address 1 replacement of a data DN-M+2 of an address 2 and a data DN-1 of an address M-1 ... replacement of a data of an address (M-1)/2 and a data of an address (M+1)/2 are executed, and an order of data extending from the address 1 to the address M is reversed. In the second process, in the same way, an order of data extending from an address M+1 to an address N is reversed[(b), (c)]and in the third process, an order of data extending from an address 1 to an address N is reversed[(c), (d)], and the rotation and movement of the data are completed by moving the data 2XN times in all.
