Abstract: A method for accessing the physical memory with an operating system, providing for mapping the physical address to the linear address of the memory in the operating system. Thus to access the user-space of the memory with an operating system is practically to read and write data in the kernel-space of the memory to achieve quick access of the physical memory.
