Abstract

PURPOSE:To improve the efficiency of programing by eliminating a microinstruction for a data transfer by performing the processing of equalizing the contents of a memory, which is performed by an accumulator and a main register in a data memory all the time, through hardware. CONSTITUTION:A clock for operating various electronic circuits is generated by a clock generating circuit 102, various microinstructions are stored in an ROM104, and various dara are stored in an RAM109. In a memory group in the RAM109, addresses of a main register and subordinate register are assigned by address assigning registers 106 and 107 respectively. With microinstructions stored in the ROM104, the arithmetic transfer, etc., of data in the RAM109 are performed by an accumulator as a working register 110. Then, the process of equalizing the contents of the memory which is performed by the register 110 and a main memory in the RAM109 at any time is carried out through hardware to eliminate a microinstruction for data transfer.
