The hardware page table walker, in response to the TLB miss indication, prefetches a physical address of a second page table entry, that provides a final physical address for the missed TLB entry, using the virtual memory region tracking information. In some implementations, the prefetching of ...
Methods and apparatus provide virtual to physical address translations and a hardware page table walker with region based page table prefetch operation that produces virtual memory region tracking information that includes at least: data representing a virtual base address of a virtual memory region and...
A page table walker (305) 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. A page size storage area (315) is used to store a number of page sizes each selected for translating a different...
The page table walker is moved from its conventional location in the memory management unit associated with the data processor to a location in main memory i.e. the main memory controller. As a result, an implementation is provided wherein the processing of requests for data could selectively ...
② itlb: instruction TLB name corresponding to this page table walker; ③ dtlb: name of data TLB corresponding to this page table walker; ④ reversed_pgt: true, enable reversed page table; false, disable reversed page table; when simulating single process, default is false; while simulating ...
A page walker cache is provided to cache data used during the page walk process. This cache structure speeds up the page walk process, which significantly reduces the expense of performing a page walk. The page walker cache also reduces the cost associated with usage of memory access bandwidth...
This proof-of-concept design uses per-compute unit TLBs, a shared highly-threaded page table walker, and a shared page walk cache... J Power,MD Hill,DA Wood - IEEE International Symposium on High Performance Computer Architecture 被引量: 75发表: 2014年 Breaking the Address Translation Wall...
Universitydavid.black-schaffer@it.uu.seAbstract—As memory capacity has outstripped TLB coverage,large data applications suffer from frequent page table walks.We investigate two complementary techniques for addressing thiscost: reducing the number of accesses required and reducing thelatency of each ...
