Bypass control circuit

Year	Description
2000	Invention patented by Tatsuo Teruyama on September 21th, 2000. Abstract: There is disclosed a bypass control method in which data can be set on a source register of an instruction to be executed on an instruction bus in a short time. A bypass control apparatus of the present invention includes a plurality of comparators for comparing the outputs of flip-flops for transferring a register number of a destination register on the instruction bus with each other. By utilizing a comparison result of a comparator for comparing the comparison results of these comparators with the register number of the source register on the instruction bus, a bypass path of data inputted to the source register of the instruction to be executed can be set in a short time. When a plurality of agreements are detected, the bypass path is set on the basis of the output of the flip-flop on a first stage side, so that it is possible to avoid a disadvantage inputting old data to the source register by mistake.
