Abstract:
The present invention relates to methods of copying and updating data in a processor memory during program run-time without suspending the program's access to its data in the memory during the data-copying and updating processes. In one aspect, the invention concerns a method of copying data from processor memory to a dump memory during run-time, including determining whether data in a segment of the processor memory is to be updated by a program and copying the data to a corresponding segment in the dump memory prior to the data being updated. According to one embodiment, a data-copying instance is utilized to obtain a point-in-time image of a data content of processor memory while the program is running.
