The embodiment of the invention provides a memory managing method and device. The method comprises the steps that data in a first available physical memory block mapped by a first available virtual memory block are copied to a physical memory block mapped by a testing virtual memory block, and the mapping relation of the first available virtual memory block and the first available physical memory block is changed to the mapping relation of the first available virtual memory block and a testing physical memory block; the mapping relation of the testing virtual memory block and the testing physical memory block is changed to the mapping relation of the testing virtual memory block and the first available physical memory block; memory detection is carried out on the first available physical memory block. The operation that the memory detection is carried out on the physical memory in the single board operation process is achieved by changing the mapping relations, the operation that the memory detection is carried out on the physical memory in the single board restarting process can be avoided or reduced, the single board restarting time is reduced, and the severity of service interruption is relieved.
Description
technical field [0001] The embodiments of the present invention relate to the technical field of communications, and in particular, to a memory management method and device. Background technique [0002] Memory is one of the most important components of communication equipment, and all programs in communication equipment run in memory. In view of the importance of memory, communication devices must ensure memory reliability during operation. [0003] In the prior art, after the single board in the communication device is started, the physical memory has a corresponding relationship with the virtual memory, and the virtual memory is uniformly addressed and managed, so the physical memory can be accessed through the virtual address of the corresponding virtual memory. When a piece of physical memory is damaged, since the virtual memory corresponding to the physical memory has been managed uniformly, this piece of physical memory will continue to be used, causing the board to ...
