PURPOSE:To shorten a processing time and to simplify control by transferring storage information in a specific area of a storage means to another storage area and rewriting the contents of a specific area of a transferring area by optional information. CONSTITUTION:The titled system is provided with a C register 21 in which optional data are set up, a selector SEL1 switching and outputting data from a shifting part 25 an the register 21 and an F selector 23 selecting and outputting a logical operation instruction and a logical operation inhibiting instruction from a function operating part 30 are connected. Consequently, the contents of a square area 2 at an address counter address are read out, processed by shift logical operation and then masked. The masked data are stored in a D address counter address of a square area 3, a SEL signal is turned off and the contents of the register 21 are stored in an S address counter address only by masking. Thus, the system is controlled so that data in the register 21 are written in the area 2 after data transfer. |
