Abstract
The present application describes a method and apparatus for filtering requests to a translation lookaside buffer (TLB). Some embodiments of the method include receiving, from a first translation lookaside buffer (TLB), an indication of a first virtual address associated with a request to a second TLB for a page table entry in response to a miss in the first TLB. Some embodiments of the method also include filtering the request based on a comparison of the first virtual address and one or more second virtual addresses associated with one or more previous requests to the second TLB.
