Abstract
PURPOSE: To perform definitely an operand data process at an address boundary with a high-speed instruction-word read from a main memory unit, by leading the output bus of an instruction buffer register to various registers required for instruction excution inside of an arithmetic processor.
CONSTITUTION: In arithmetic controller 3 which constitutes an instruction executed, after being read out from memory board 1 by way of memory board 1, main memory unit, stored with instruction and data word by word and memory board control part 2, as long as the length obtained by multiplying a half word, word-unit instructions read out from memory board 1 are stored temporarily in an instruction buffer register inside of memory data control part 6. Then, the output of this instruction buffer register is made into the half-word bus constitution. Under the control of the instruction address register inside of memory address control part 3, the output bus of the instruction buffer register is led to various registers required for instruction execution in the arithmetic controller.
