PA in memory virtualization is a machine address. Virtual memory is a technology for computer system memory management. It makes applications consider it to have a continuous and available memory space for continuous memory. In fact, it is usually separated into Multiple physical memory fragments, and some are temporarily stored on external disk memory, and data exchange is performed when needed. The principle of virtual memory Stock memory is automatically realized by the hardware and operating system to automatically store the storage information scheduling and management. The logical address of the central processor visitor the main memory of the main memory is decomposed into a group number A and the internal address B, and the address transformation of the group number A will be transformed. Inside the main memory. If the group number is in the main memory, it will be executed. If the group number is not in the main memory, check whether there is a free zone in the main memory. Send it to the auxiliary deposit so that this set of information is transferred to the main memory. The groups you want from the auxiliary deposit, and send it to the main memory area, and then log in to the idle physical group number A and logic group number A in the address transformation table. The physical group number A corresponding to the logic group number A from the address transformation table, from the physical group number A and in -group bytete address B to obtain the physical address, and the necessary information is accessible from the main memory according to the physical address Essence

The principle of virtual memory
Stock memory is automatically realized by the hardware and operating system to automatically store the storage information scheduling and management. The logical address of the central processor visitor the main memory of the main memory is decomposed into a group number A and the internal address B, and the address transformation of the group number A will be transformed.
