摘要：The object of the present invention is to provide a garbage collection (GC)system that suppresses wasteful increase in CPU time required for GC, without stoppingall AP threads for an excessively long amount of time. The garbage collection systemfrees memory areas corresponding to objects that are no longer required in an executionprocedure of an object-oriented program composed of a plurality of threads, andincludes: a selection unit operable to select the threads one at a time; an examination unitoperable to execute examination processing with respect to the selected thread, theexamination processing including procedures of stopping execution of the thread, findingan object that is accessible from the thread by referring to an object pointer, managingthe found object as a non-freeing target, and resuming execution of the thread; adetection unit operable to, when having detected, after the selection unit has
commenced selecting, that an object pointer has been processed as a processing targetby a currently-executed thread, manage an object indicated by the processing targetobject pointer, as a non-freeing target; and a freeing unit operable to, after theexamination processing has been completed with respect to all of the threads, free
memory areas that correspond to objects other than the objects that are managed asnon-freeing targets.
