Abstract:
A processor includes a translation lookaside buffer (TLB) to store a TLB entry, wherein the TLB entry comprises a first set of valid bits to identify if the first TLB entry corresponds to a virtual address from a memory access request, wherein the valid bits are set based on a first page size associated with the TLB entry from a first set of different page sizes assigned to a first probe group; and a control circuit to probe the TLB for each page size of the first set of different page sizes assigned to the first probe group in a single probe cycle to determine if the TLB entry corresponds to the virtual address from the memory access request.
