Method for combining card marking with remembered set for generational garbage collection with more than two generations

摘要: A system for garbage collection of memory objects in a heap. The includes heap that is partitioned into few generations, each generation being cards. generations are associated with remembered sets and card markings data structure. Each the structure scan related represent which has or not to be scanned. further processor communicating scanning cards according data, response identifying updated inter-generational pointers, capable updating remember set identified pointers. data.
