Abstract
A method and system for purging translation lookaside buffers (TLB) of a computer system are described. Directed write transactions can be used to avoid deadlock and avoid the need for additional bridge buffers. Broadcast emulation can be achieved by linking the nodes in a doubly-linked list and having neighboring nodes notify each other of changes in TLB entries.
