摘要： A method for performing rapid memory management unit emulation of a computer program in a computer system, wherein address injection space of predefined size is allocated in the computer system and a virtual page number and a corresponding physical page number are stored in said address injection space, said method comprising steps of: comparing the virtual page number of the virtual address of a load/store instruction in a code segment in said computer program with the virtual address page number stored in said address injection space; if the two virtual page numbers are the same, then obtaining the corresponding physical address according to the physical page number stored in said address injection space; otherwise, performing address translation lookaside buffer search, that is, TLB search to obtain the corresponding physical address; and reading/writing data from/to said obtained corresponding physical address. The present invention also provides an apparatus and computer program product for implementing the method described above.
