Pointing manner because of check in the speculation bajiyoningu cache, the computer program, and the computer system (check pointing in speculation bajiyoningu cache)

摘要

Topic Feature in order to generate checkpoint (1030) inside the speculation bajiyoningu cache (310 and 1210) of the computer system (100) is offered.Solutions Feature runs the code inside the computer system, (100) accesses the code, the cache line inside the speculation bajiyoningu cache (310 and 1210). Furthermore it decides feature, (1350) whether or not the 1st condition for showing the necessity which generates checkpoint (1030) inside the speculation bajiyoningu cache (310 and 1210) is generated. Checkpoint (1310) responding to the generation of the 2nd condition for needing the rollback of alteration to the cache line which corresponds to the speculation cache line, non becomes speculation, it is the speculation cache line. Feature, responding to the decision of the effect where 1st condition is generated, generates also checkpoint (1310) inside the speculation bajiyoningu cache (310 and 1210). Choice figure Drawing 12
