Using dynamic compilation for continuing execution under reduced memory availability
This paper explores the use of dynamic compilation for continuing execution even if one or more of the memory banks used by an application become temporarily unavailable (but their contents are preserved), that is, the number of memory banks available to the application varies at runtime. We implemented the proposed dynamic compilation approach using a code instrumentation system and performed experiments with 12 embedded benchmark codes. The results collected so far are very encouraging and indicate that, even when all the overheads incurred by dynamic compilation are included, the proposed approach still brings significant benefits over an alternate approach that suspends application execution when there is a reduction in memory bank availability and resumes later when all the banks are up and running. © 2009 EDAA.
