摘要
操作系统中内核管理的重要资源是内存,在多用户的操作系统中,按照内存页的形式进行内存管理,有时会出现内存页被耗光的情况,所以操作系统的内存管理的任务不仅是内存的分配,更重要的是页面回收和更新进程的页表项。对基于对象的反向映射机制与页面回收算法相结合来实现内存页的管理进行研究,减少系统时间消耗和空间消耗,可以更好地提高系统工作效率。
Memory is an important resource of kernel management in an operating systems. In a multi-user operating system, memory management based on memory pages will sometimes use up the memory page. Therefore the memory management an operating system is not merely the memory task distribution, more importantly; it is the recovery and updating of process page table entry page. The study of object-based reverse mapping mechanism in combination with the page collection algorithm to achieve the management of memory pages can reduce system time and space consumption, and can better improve the system efficiency.
