The invention can ensure successful physical memory allocation in the drive of the embedded system, and can avoid system exception caused by the failure of applying for continuous physical memory.
本发明能够确保嵌入式系统驱动中连续物理内存分配成功，并且避免由于申请连续物理内存失败而出现系统异常的情况。
Loading precompiled headers requires allocation of physical memory, which can be a problem if you are compiling on a computer with limited RAM.
加载预编译头需要分配物理内存，如果您正在一台RAM有限的计算机上进行编译，这可能会是一个问题。
So, the physical DRAM is used only when it absolutely has to be, and the kernel controls the allocation through a global memory management scheme.
因此，只有在万不得已时才用到物理DRAM，内核通过全局内存管理模式控制分配。
The advantage of allocation mechanism is that once physical memory is allocated operating system can't reclaim it until either the process is terminated or the process frees memory back to the OS.
这种分配机制的好处是不会被系统回收，直到进程终止或者进程内存被释放会操作系统。
