Abstract
A method for use in a multiprocessor computer system where data objects larger than the address space of a single task are mapped in main memory and the translation lookaside buffer (TLB) is maintained by user mode software is disclosed. The method uses lazy TLB updating that allows stale data to stay in the TLB until it needs to be purged.
