Apparatus and method for memory overlay
A memory overlay apparatus includes an internal memory that includes a dirty bit indicating a changed memory area, a memory management unit that controls an external memory to store only changed data so that only data actually being used by a task during overlay is stored and restored, and a direct memory access (DMA) management unit that confirms the dirty bit when the task is changed and that moves a data area of the task between the internal memory and the external memory.
