S2, the hardware can recognize that the instruction of instruction and instruction buffer storage whether there is similar instruction, if depositing
The hardware then can recognize that to the corresponding similar instruction of instruction replacement instruction buffering area storage；If being not present, judgement refers to
Make buffering area whether store full, if storage is full, the hardware can recognize that the of described instruction buffering area is replaced in instruction
One instruction, if storage less than, by the hardware can recognize that instruction write-in described instruction buffering area.
Specifically, in embodiments of the present invention, the hardware can recognize that every of instruction and instruction buffer storage
Whether instruction is there are similar instruction, is specifically included：Compare the hardware and can recognize that corresponding device number and instruction are slow in instruction
Whether identical corresponding device number in the instruction of area's storage is rushed, when the hardware can recognize that corresponding device number and instruction in instruction
Corresponding device number is identical in the instruction of buffering area storage, then there are similar instruction；Corresponded to when the hardware can recognize that in instruction
Device number device number corresponding with the instruction that instruction buffer stores differ, then there is no similar instruction.For same
The distinct device (such as the equipment such as fan on experimental box, tri coloured lantern) of one hardware is both provided with different device numbers, device number
It is indicated with integer, device number can be embodied in hardware and can recognize that in instruction.In this way, the present invention is achieved that hardware can be known
Zhi Ling not be with the judgement and replacement of similar instruction in instruction buffer.
