METHOD FOR ALLOCATING HEAP MEMORY OBJECTS AND HYBRID MEMORY SYSTEM IMPLEMENTING THE SAME

摘要

As a heterogeneous memory system, a memory device composed of a first memory and a second memory of a different type from the first memory, a heap memory object placed by the application program on the memory device when a profiling request is received from an application program ( a memory profiling unit that extracts access information for accessing the first memory and the second memory, respectively, and the heap memory object is disposed in the first memory and the second memory using the access information. And an energy predicting unit for determining the predicted energy consumption, and a placement determining unit for determining whether to place the heap memory object in the first memory or the second memory according to the energy consumption.
