摘要： A method and apparatus for implementing a page table walker that uses at least one of a default page size and a page size selected for a virtual address space to position a sliding field in a virtual address. According to one aspect of the invention, an apparatus for use in a computer system is provided that includes a page size storage area and a page table walker. The page size storage area is used to store a number of page sizes each selected for translating a different set of virtual addresses. The page table walker includes a selection unit coupled to the page size storage area, as well as a page entry address generator coupled to the selection unit. For each of the virtual address received, the selection unit positions a field in that virtual address based on the page size selected for translating the set of virtual addresses to which that virtual address belongs. In response to receiving the bits in the field identified for each of the virtual addresses, the page entry address generator identifies an entry in a page table based on those bits.
摘要翻译：一种用于实现使用为虚拟地址空间选择的默认页面大小和页面大小中的至少一个来定位虚拟地址中的滑动字段的页表行进者的方法和装置。根据本发明的一个方面，提供了一种在计算机系统中使用的装置，其包括页面大小存储区域和页表行进器。页面大小存储区域用于存储每个被选择用于翻译不同虚拟地址集合的页面大小的数量。页表步行器包括耦合到页面大小存储区域的选择单元以及耦合到选择单元的页面输入地址生成器。对于接收到的每个虚拟地址，选择单元基于为了翻译该虚拟地址所属的虚拟地址集而选择的页面大小来定位该虚拟地址中的字段。响应于接收到为每个虚拟地址标识的字段中的比特，页面入口地址生成器基于这些比特识别页表中的条目。
