GARBAGE COLLECTION SYSTEM

摘要

It is possible to suppress increase of the time required for garbage collection without prolonging the all-sled stop period of AP. A garbage collection system includes: selection means for successively selecting a plurality of sleds in the execution process of the object-orientated program consisting of a plurality of sleds; inspection means for performing inspection processing for stopping the execution of the sled selected, detecting an object accessible from the sled so as to be managed as a non-release object, and resuming execution of the sled; detection means for detecting that an object pointer is made a processing object by the sled in execution after the start of the selection by the selection means and making the object specified by the object pointer a non-release object; and release means for releasing a memory area corresponding to an object other than the object managed as a non-release object after completion of the inspection processing for all the sleds.
