The garbage collection method and garbage collection system bounded pause time has write barriers and read barrier associated with an instance of the object is relocated partially

摘要

(57) by the object identifier store read barrier logic and [summary] writing has been relocated partially including an accessible copy to identifier storage and copy from, read barrier logic and write, partial re-arrangement of the memory object On the basis of the state, it is possible to selectively directed to the appropriate instance of ToSpace or FromSpace instance of memory objects that have been relocated partially, the load-oriented access and store-oriented access. Barrier of these, in some embodiments, put a trap to trap handler object that has been relocated partially. In another embodiment, without software overhead, write barriers to carry out its own direct access. Also, by how far the display storage provided optionally with a barrier logic, or between the portions which are not copied and the copied portion of the memory objects are rearranged in part by an object trap handler rearranged partially distinction becomes easy.
