"Two schemes for handling TLB misses are commonly found in modern architectures: • With hardware TLB management, the CPU automatically walks the page tables (using the CR3 register on x86, for instance) to see whether there is a valid page-table entry for the specified virtual address. If an entry exists, it is brought into the TLB, and the TLB access is retried: this time the access will hit, and the program can proceed normally. If the CPU finds no valid entry f… " - Hardware vs software tlb
