Abstract
A method for performing garbage collection for a real-time application uses a memory for determining an amount of memory required to run the garbage collection process and waits until the determined amount of memory is available, then allocates memory space for the application by segmenting the memory space into a number of pages of a predetermined size. A mutator is used for assuring that only non-null, unmarked objects are placed into a write buffer. A hybrid collector is used for removing the dead objects and defragmenting the memory space.
