help optimize your system's performance, especially if you frequently run memory-intensive applications. however, it's important to use discretion, because setting the virtual memory too high or too low can neg
memory Hierarchical paging One way is to use a two-level paging algorithm Hierarchical paging Remember the example is a 32-bit machine with a page size of 4 KB. A logical address is divided into a page number consisting of 20 bits and a page ...
Second Chance Page Replacement Algorithm 基于前面的FIFO Page Replacement Algorithm,A页面是最先进入到内存的页面,当需要替换页面的时候找到A,然后检查A的Referenced位,如果被置1,则将A放到队尾并将Referenced清0,若此时的队头是B,且B的R位没有被置则将其替换。 等到再次轮到A的时候,发现A的R位没...

ところが、linuxおよび、xv6では、code部分、data部分のBase addressを同じ0x00000000に指定することで、実質的にsegmentationの分離機能を打ち消してしています9。(paging機能が、memory managementの役割を担っています) 上図で言うと、"logical address"と"linear address"が全く同じになります。こ...
the linear addresses generated by the segmentation unit are simply transferred through the paging unit and utilized without change as the physical addresses for accessing information in memory. Details of the addressing arrangement of the microprocessor are provided in a publication entitled i486, publish...
