An original first instruction word (I1) to an original third instruction word (I3) include a bit field (L11) and a bit field (L12) to a bit field (L31) and a bit field (L32). An information word (IW) includes a set of some of bit fields belonging to a plurality of instruction words executed in the same cycle, which are the bit field (L12) of the original first instruction word (I1) to the bit field (L32) of the original third instruction word (I3). An instruction decoder (103) of a processor (100) decomposes the information word (IW) and restores the arrangements of the original first instruction word (I1) to the original third instruction word (I3) by combining the bit field (L11) to the bit field (L31) to the bit field (L12) to the bit field (L32). This can reduce the amount of memory consumption without degrading the instruction execution performance.
A processor characterized by decomposing, at the time of execution, an information word comprising a set of some of bit fields belonging to a plurality of instruction words executed in the same cycle, and restoring each instruction word into an original arrangement.
An instruction control method characterized by comprising the step of causing a processor to decompose an information word comprising a set of some of bit fields belonging to a plurality of instruction words executed in the same cycle at the time of execution and restore each instruction word into an original arrangement.
A program for causing a processor to execute the step of decomposing an information word comprising a set of some of bit fields belonging to a plurality of instruction words executed in the same cycle at the time of execution and restoring each instruction word into an original arrangement.
A program according to 17, which causes the processor to further execute the steps of
