ABSTRACT:
The alignment of data as required in an L-stage is carried out with a first aligner which is controlled by a wired logic for exclusive use, while the alignment of data as required in an E-stage is carried out with a second aligner which is controlled by a microinstruction. Regarding those among macroinstructions which need to fetch storage operands in only the L-stages, the alignment of the storage operand is carried out by means of the first aligner. On the other hand, in the execution of macroinstructions which need to fetch storage operands in both the L-stages and the E-stages, the storage operands fetched in the L- and E-stages are respectively aligned by means of the first and second aligners.
