Abstract
A computer system includes a physical memory having a first page table and a second page table, and an address translation module. The first page table includes primary page table entries, where each page table entry among the primary page table entries is configured to store a mapping of a virtual memory address to a physical memory address and auxiliary information. The second page table includes secondary page table entries each storing at least one further auxiliary information, where each secondary page table entry corresponds to a primary page table entry in the first page table. The address translation module is configured to, in response to receiving a request from a processor, walk through the first page table to identify a primary page table entry and consecutively identify a location of a corresponding secondary page table entry based on a location of the primary page table entry.
