IPC: G06F9/34
Filed: 1989-05-10
Abstract: PURPOSE:To take an operand out speedily by using two buffer storage devices when one memory operand that an instruction requires is present successively in two words. CONSTITUTION:A decoder 2 decodes an instruction and decides whether or not the instruction requires only one memory operand. A control circuit 11 inputs the output of a register 8, i.e. memory operand length and part of the output of a register 9, i.e. the in-word address of the memory operand and decides whether or not the memory operand is present successively in two words. When it is decided that the operand is present in two words, the word where the head of the memory operand is present is read out of a 1st buffer storage device 19 under the control of the control circuit 11 and a next word of the word where the head is present is read out of a 2nd buffer storage circuit 20. Consequently, the takeout time for the memory operand is shortened.
