APPARATUS FOR MEMORY MANAGEMENT AND METHOD

摘要

PURPOSE: An apparatus for memory management and a method thereof are provided to reduce the overhead in the copy of task related data for an external memory or an on-chip memory in a multitasking environment. CONSTITUTION: A control unit divides an external memory region into a first region and a second region. The region of the external memory is allocated to a task, and a second control unit load the data of the first region to an internal memory while a processor(210) performs the task. Whenever the task is changed, a memory management device selects the region of data. The data region is copied to the region between an internal memory(220) and an external memory(230).
