Abstract
In one illustrative embodiment, an apparatus for controlling a translation lookaside buffer is provided. The apparatus comprises a translation unit, a buffer, and a comparator. The translation unit is adapted to initiate a table walk process to convert a virtual memory address to a physical address. The buffer is adapted to store pending memory access requests previously processed by the translation unit. The comparator is adapted to determine if a physical address generated by the table walk process of the translation unit conflicts with a physical address of at least one of the pending memory access requests, and deliver a control signal to the translation unit for canceling the table walk process in response to determining that a conflict exists.
