摘要：
In one embodiment, a processor comprising at least one translation lookaside buffer (TLB) and a control unit coupled to the TLB. The control unit is configured to track whether or not at least one update to the TLB is pending for at least one of a plurality of strands. Each strand comprises hardware to support a different thread of a plurality of concurrently activateable threads in the processor. The strands share the TLB, and the control unit is configured to delay a demap operation issued from one of the estrands responsive to the pending update, if any.
