Method for automatic page table compression

摘要

One embodiment of the present invention sets forth a technique for performing a method for compressing page table entries (PTEs) prior to storing the PTEs in a translation look-aside buffer (TLB). A page table entry (PTE) request is received for a PTE that is not stored in the TLB. The PTE as well as a plurality of PTEs that are adjacent to the PTE are retrieved from a memory. The PTE and the plurality of PTEs are compressed and then stored in the TLB.

1. A method for compressing page table entries (PTEs) prior to storing the PTEs in a translation look-aside buffer (TLB), comprising:
receiving a page table entry (PTE) request for a PTE that is not stored in the TLB; retrieving, from a memory, the PTE as well as a plurality of PTEs that are adjacent to the PTE; compressing the PTE and the plurality of PTEs into a single cache line; and storing the cache line in the TLB.
