Abstract: 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.

Abstract translation: 一种装置包括翻译后备缓冲器（TLB）。 TLB包括至少一个条目，其包括条目虚拟地址和对应于条目页面的条目页面大小指示。 该装置还包括被配置为接收输入页面大小指示和与输入页面相对应的输入虚拟地址的输入逻辑。 该装置还包括重叠检查逻辑，其被配置为至少部分地基于条目页面大小指示和输入页面大小指示来确定输入页面是否与入口页面重叠。
