Description
Technical field
The embodiment of the present invention relates to computer memory technical field, particularly relates to a kind of visit information disposal route to memory device and device, system.
Background technology
In the prior art, mainly comprise two kinds to the access method of storage medium, first method is by kernel access storage media, the system architecture diagram of a kind of access method to storage medium that Fig. 8 provides for prior art, as shown in Figure 8:
Virtual address is sent to memory management unit (Memorymanagementunit by core, MMU), MMU query conversion query caching (Translationlookasidebuffer, TLB) is shown, and finds that the virtual address that will access also does not have physical address corresponding with it.MMU sends out page faults to core, core response is interrupted, after protection running environment, be absorbed in kernel, physical memory allocator (being arranged in operating system OS as shown in Figure 8) in kernel is this virtual address allocated physical address, and set up page table, wherein, the corresponding relation between the virtual address of foundation and physical address is preserved in page table, page table is loaded into TLB table, namely TLB table is refreshed, kernel sends interrupt routine to core and completes, core recovering process running environment, again virtual address is sent to MMU, MMU inquires about TLB table, obtain the physical address that virtual address is corresponding, MMU sends and comprises physical address request of access to buffer memory (cache), cache sends access request to Memory Controller Hub, Memory Controller Hub is to dynamic RAM ((DynamicRandomAccessMemory, DRAM) request of access is sent, DRAM responds request of access, if read then by data from DRAM through Memory Controller Hub, cache directly arrives core.
