    • Methods, devices, and instructions for performing a reverse translation lookaside buffer (TLB) look-up using a physical address input, including obtaining with a first processor the physical address input, wherein the physical address input indicates a physical address corresponding to a shared memory, obtaining a first mask associated with a first virtual address from a first TLB entry within a TLB associated with the first processor, wherein the obtained first mask is a bit pattern, obtaining from the first TLB entry a first page frame number associated with the shared memory, applying the obtained first mask to the obtained first page frame number to generate a first value, applying the obtained first mask to the obtained physical address input to generate a second value, and comparing the first value and the second value to determine whether the first value and the second value match.
    • 用于使用物理地址输入来执行反向翻译后备缓冲器(TLB)查找的方法,设备和指令,包括用第一处理器获取物理地址输入,其中物理地址输入指示对应于共享存储器的物理地址 从与所述第一处理器相关联的TLB内的第一TLB条目获得与第一虚拟地址相关联的第一掩码,其中所获得的第一掩码是位模式,从所述第一TLB条目获得与所述共享信息相关联的第一页框号 存储器,将所获得的第一掩模应用于获得的第一页帧号以产生第一值,将获得的第一掩码应用于获得的物理地址输入以产生第二值,并且比较第一值和第二值以确定是否 第一个值和第二个值匹配。
