发明名称 OVERLAP CHECKING FOR A TRANSLATION LOOKASIDE BUFFER (TLB)
摘要 An apparatus includes a translation lookaside buffer (TLB). The TLB includes at least one entry that includes an entry virtual address and an entry page size indication corresponding to an entry page. The apparatus also includes input logic configured to receive an input page size indication and an input virtual address corresponding to an input page. The apparatus further includes overlap checking logic configured to determine, based at least in part on the entry page size indication and the input page size indication, whether the input page overlaps the entry page.

主权项 1. A method comprising: receiving an input virtual address and an input page size indication at a translation lookaside buffer (TLB), the input virtual address and the input page size indication corresponding to an input page; determining a computed page size based on a comparison of the input page size indication to an entry page size indication of an entry of the TLB, wherein the entry of the TLB corresponds to an entry page; and performing a masked comparison, based on the computed page size, of the input virtual address to an entry virtual address of the entry to determine whether the input page overlaps the entry page.
