It carries, dispatcher's board generates timing node B after receiving valid instruction, and node B is sent to the matching of black area disk to cache
It extracts, since a valid instruction can generate node A in the disk of black area, node B, therefore, AB node is generated in dispatcher's board
After matching, the data cached of the valid instruction will be extracted, and illegally instruct due to not obtaining legal approval, just not had
Timing node B, then, these lack cache information corresponding with timing node B and are just in non-readable guard mode always,
Belong to the cache information that can not be called, would not also be extracted away, by carrying out cleaning setting to disc cache, does not have for a long time
There is be extracted data cached to be fallen by periodic cleaning, and then reduce the EMS memory occupation and work load of disc cache, when due to using
Extraction is protected and matched to the mode of intermediate node to data cached, although instruction is by Out-of-order execution, on the whole also
It is that the instruction first received is first carried out, the matching of timing node is also just time-consuming less, and therefore, this protected mode can't
Reduce the processing speed of general purpose microprocessor.
