Abstract
A processor architecture utilizing a L3 translation lookaside buffer (TLB) to reduce page walks. The processor includes multiple cores, where each core includes a L1 TLB and a L2 TLB. The processor further includes a L3 TLB that is shared across the processor cores, where the L3 TLB is implemented in off-chip or die-stack dynamic random-access memory. Furthermore, the processor includes a page table connected to the L3 TLB, where the page table stores a mapping between virtual addresses and physical addresses. In such an architecture, by having the L3 TLB with a very large capacity, performance may be improved, such as execution time, by eliminating page walks, which requires multiple data accesses.
