记忆池 (Memory Pool)，又被称为固定大小区块规划 (fixed-size-blocks allocation)，允许程序员以类似 C语言 的 malloc 或是 C++ 的 new 算子进行动态的内存规划。对于其它动态内存规划的实践来说，因为会变动内存区块大小导致的碎片问题，导致在实时系统上受限于性能因此，根本无法使用。记忆池'提供了一个更有效率的解决方案：预先规划一定数量的内存区块，使得整个程序可以在运行期规划 (allocate)、使用 (access)、归还 (free) 内存区块。

Memory pools, also called fixed-size blocks allocation, is the use of pools for memory management that allows dynamic memory allocation comparable to malloc or C++'s operator new. As those implementations suffer from fragmentation because of variable block sizes, it is not recommendable to use them in a real time system due to performance. A more efficient solution is preallocating a number of memory blocks with the same size called the memory pool. The application can allocate, access, and free blocks represented by handles at run time.
