SUB PAGE AND PAGE MEMORY MANAGEMENT APPARATUS AND METHOD |
摘要 |
<p>A method and apparatus for managing a virtual address to physical address translation utilize a subpage level fault detecting and access. The method and apparatus may also use an additional subpage and page store Non- Volatile Store (NVS). The method and apparatus determines whether a page fault occurs or whether a subpage fault occurs to effect an address translation and also operates such that if a subpage fault had occurred, a subpage is loaded corresponding to the fault from a NVS to a DRAM, such as DRAM or any other suitable volatile memory historically referred to as main memory. The method and apparatus, if a page fault has occurred, determines if a page fault has occurred without operating system assistance and is a hardware page fault detection system that loads a page corresponding to the fault from NVS to DRAM.</p> |
