Abstract
A multiprocessor which shares the memory among processors and uses multiples translation lookaside buffers (TLBs) can face various problems. One such problem is the problem of inconsistency which may occur when the page table entry (PTE) is updated because of the multiple copies of same page table entry in various TLBs. Commonly, the inconsistency problem exists in virtually tagged caches, which keep page table entry information, like reference bit, dirty bit and protection bit, in every cache line (Agarwal et al Inconsistency in translation lookaside buffer, 2016 [1]). This paper presents concurrency control algorithms for translation lookaside buffer. We focus on algorithms that reduce the access rights to a page without causing the TLB inconsistency problem.
