ABSTRACT:
An improved method and apparatus for utilizing Translation Lookaside Buffers (TLB) for maintaining page tables in a paging unit on a computer system. TLB contents for executing tasks are retained when the task is swapped out. The contents are then reloaded into the TLB when the task is again scheduled for execution. Spare memory cycles are utilized to transfer outgoing TLB data into memory, and incoming TLB data for a next scheduled task from memory.
