Abstract: A method and an apparatus for querying a physical memory address where the method includes storing, into a prefetch buffer, page table entries of a second thread that is to perform addressing that are stored in a standby buffer, where the standby buffer stores page table entries that are not queried within a set time in a translation lookaside buffer (TLB), receiving a memory addressing request message that carries a virtual address and is sent by the second thread, and querying, in the TLB and the prefetch buffer, a corresponding physical address according to the virtual address.

Abstract translation: 一种用于查询物理存储器地址的方法和装置，其中所述方法包括将预取缓冲器存储在要执行寻址的第二线程的页表条目中，所述寻址存储在备用缓冲器中，其中备用缓冲器存储页表项 在翻译后备缓冲器（TLB）中在设定的时间内不查询，接收携带虚拟地址并由第二线程发送的存储器寻址请求消息，并且在TLB和预取缓冲器中查询对应的物理 地址根据虚拟地址。
