Patent Classification: ["711", "207000"]

Abstract:
The disclosure provides an approach for tracking metadata (e.g., accessed and dirty bits) of page tables at finer granularity than the size of the page tables. A disclosed herein, modification to existing hardware design may enable finer page table granularity of metadata, leading to more precise representation of the state of memory and an improvement to system performance and efficiency. Finer grain dirty metadata can dramatically improve the efficiency and simplicity of subsystems.

Claim (Index 17):
A system comprising a central processing unit (CPU) and memory, wherein the system is configured to translate a virtual address to a physical address using memory pages with size of a memory page magnitude, the CPU configured to track metadata with a metadata granularity magnitude that is smaller than the memory page magnitude, wherein the system is further configured to:\n receive an operation to be performed on data stored at the virtual address; locate a page table entry (PTE) within a page table based on the virtual address, the PTE containing a frame number, the frame number pointing to a portion of memory; locate a metadata registry entry (MRE) within a metadata registry (MR) that corresponds to the PTE based on the virtual address, the MRE containing metadata for the portion of memory; and update the metadata in the MRE based on the operation.
