Memory management method in embedded system

A memory management method, comprising:

• sequentially allocating and deleting, by a processor, memory starting from a first hollow space and recognizing, by the processor, an area when the memory is allocated as a hollow space list at initial iteration;
• when the hollow space list is recognized, allocating and deleting, by the processor, the memory in the area of the hollow space list;
• and
• when the hollow space list is expanded and re-recognized due to the hollow space list being insufficient, deleting, by the processor, the allocated memory, initializing the hollow space list, and then sequentially allocating the memory from the first hollow space.

A non-transitory computer readable medium containing program instructions executed by a processor or controller, the computer readable medium comprising:

• program instructions that perform a first iteration of sequentially allocating and deleting memory and recognizing an area when the first to last sections of the memory were located as a hollow space list;
• program instructions that perform a second iteration of sequentially allocating, the memory in an area of the hollow space list by starting memory allocation from an end point of the hollow space list, when the hollow space list is insufficient during the memory allocation, allocating a memory section outside the area of the hollow space list, re-recognizing the hollow space list by expanding to the area when the last section of the memory was located, when the hollow space list is sufficient during the memory allocation, maintaining the hollow space list, and sequentially deleting the allocated memory;
• and
• program instruction that initialize the hollow space list when the hollow space list is re-recognized.
