Abstract: The present invention discloses an application of chebulinic acid in preparation of anti-rotavirus drugs, which belongs to the technical field of anti-rotavirus drugs. Chebulinic acid has the effect of resisting rotavirus biosynthesis, has no effect of resistance to rotavirus adsorption and direct killing, and can inhibit the gene expression of VP6 to play an anti-RV role. Network pharmacology analysis indicates that chebulinic acid acts on rotavirus-related genes. Compared with the prior art, the present invention has the beneficial effects that: the present invention relates to an application of chebulinic acid in preparation of anti-rotavirus drugs.

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.
