Abstract

A dynamic memory management method suitable for a memory allocation request of various applications can include predicting whether an object for which memory allocation is requested is a short-lived first type object or a long-lived second type object by using index information relating to the size of the object; determining whether a heap memory includes a free block that is to be allocated to the object by using a plurality of free lists that are classified as a plurality of hierarchical levels; and allocating the free block to the object if the heap memory is determined to include the free block, wherein, if the object is predicted to be the first type object, the free block is allocated to the object in a first direction in the heap memory, and, if the object is predicted to be the second type object, the free block is allocated to the object in a second direction in the heap memory.

Description

[0001] This application claims the priority of Korean Patent Application No. 10-2009-0011228 filed at the Korean Intellectual Property Office on February 11, 2009, and the entire contents of the disclosure are incorporated herein by reference. Technical field [0002] Various embodiments relate to an embedded system including a memory management unit, and more specifically, to an embedded system including a memory management unit that dynamically allocates memory. Background technique [0003] Memory management can directly affect the performance of embedded systems including microprocessors. Generally, in order to execute various application programs in the microprocessor, the memory management allocates and frees a part of the memory of the embedded system for each application program. Memory allocation operations are divided into static memory allocation operations and dynamic memory allocation operations. [0004] Static memory allocation operations use a fixed amount of memory...
