  • Publication number: 20100153678
    Abstract: Disclosed is a memory management apparatus and method. The memory management apparatus includes a memory, an asymmetrical multi-core processor in which a core having a memory management unit and a core not having a memory management unit exist together, and a memory allocation processing unit. The memory allocation processing unit collects memory fragments dispersed in the memory into one consecutive area in response to the memory allocation request from the core not having the memory management unit and then allocates the one collected consecutive area to the corresponding cores. The one consecutive area is formed by moving the memory areas that are being used by the core having the memory management unit.
