Memory management system for reducing memory fragmentation

A memory management system for a process formulated in the C/C++ language in a processing unit, this system comprising:

• an allocator, allocates memory spaces for the objects which the process uses, and of freeing memory spaces which the process does not use to the operating system of the processing unit;
• an asynchronous mechanism, which defines a buffer zone consisting of a set of memory blocks which are available for the process, all the memory blocks of said mechanism being of the same size, equal to m*32 kilobytes, where m is between 1 and 4;
• each memory block of m*32 kilobytes, originated from said mechanism and used by the process, is managed by the allocator in the form of memory regions, according to the “chunk” memory management technique;
• for large objects, the size of which is within a predetermined size range, each memory block of m*32 kilobytes is considered as a multi-size memory region (chunk), which includes several of said large objects of different sizes, said multi-size memory region (chunk) containing a header indicating that this is a memory region (chunk) including large objects, a bit field, and a data area comprising small memory blocks in the course of usage and free small memory blocks, the small memory blocks of the multi-size memory region (chunk) being all of the same size;
• the allocator comprising means of implementing the de Bruijn algorithm, in combination with the bit field technique, to determine the adjacent free blocks, when the process frees a small memory block.
