Abstract

PURPOSE: The transfer of data groups in the main memory is realized thru a special command method applying firmware technologies, and the prohibitinterrupt condition while executing special commands is eliminated. Interrupt permsssion is given for the transfer of each data word with fewer pieces of hardware, and data groups are transferred at a high speed.
