Bounded pause time garbage collection system and method including write barrier associated with the source instance of a partially relocated object

摘要

(57) For example, copy collector, generation specific collector, and write barriers to the store in the memory objects frequently accessed or large that has been relocated [summary] partially, relocation, including the collector with a shortened function I to facilitate the implementation bounded pause time of garbage collector. Writing such barriers, to coincide with bounded pause time, it is possible to interrupt the relocation of the memory object operation garbage collector implementation frequently accessed or large. By the object identifier store that is relocated partially including the accessible "copy from" identifier storage to write barrier logic, and between the ToSpace instance FromSpace instance of memory objects that have write barrier logic, has been re-placed partially it is possible to maintain consistency. By the "Copy from" identifier storage, it is possible to trap handler to respond to it or write barrier, broadcast to both the ToSpace instance FromSpace instance store-oriented memory access, which targets FromSpace instance. The optional "How far" indication storage facilitates differentiation by the write barrier logic between a part that has not been copied and the copied portion of the memory objects are rearranged in part.
