    Abstract: A context switch method capable of promptly switching a context for a dynamically generated task and a dynamic link by converting a state of multiple register files, switching the context, and separately restoring and storing the context. That is, the context switch method includes: maintaining a multiple register files; establishing the multiple register to be in any one of a prefetch state, a current state, and a store state; converting a state of the multiple register files to be in any one of the prefetch state, the current state, and the store state when a context switch occurs; wherein, in the prefetch state, determining a memory address to read a next task context to be subsequently performed by the register file, in the current state, performing a task with the task context of the register file and in the store state, storing the register file in a memory.

    Abstract: An apparatus for managing memory in a real-time embedded system and a method of allocating, deallocating and managing memory in a real-time embedded system. The apparatus includes a defragmentation unit performing a defragmentation task according to a predetermined priority to collect together memory fragments, and a memory manager allocating or deallocating a predetermined area of memory upon request of a task, and calculating a memory fragmentation rate of the memory to determine a priority of the defragmentation task. The method of managing memory in a real-time embedded system includes determining whether the conditions under which the memory is used vary, and if the condition vary, calculating a memory fragmentation rate of the memory to determine a priority of the defragmentation task according to the memory fragmentation rate.
