Abstract

PURPOSE: To achieve high speed transfer instruction having also a copy function, by realizing the comparison of addresses without comparison of addresses directly.
CONSTITUTION: A data bus 4 connecting a memory 1, an input/output device 2, a central processing device 3 and each device, a source area 5 in L-byte started from an SA designated with a transfer instruction, and destination area 6 in L-byte started from a DA designated with the transfer instruction are provided. Further, the transfer instruction, i.e., an instruction having a function transferring a data in an arbitrary area in the memory is provided. To realize this instruction with a microprogram, the instruction is transferred to the area 6 from the SA one by one-byte and this is repeated by L times, or several bytes are transferred and the number of times of repetition is decreased for high speed transfer.
