PROBLEM TO BE SOLVED: To share a buffer for address conversion (TLB: Translation Lookaside Buffer) among a plurality of threads without generating unnecessary multi-hit in an information processor which operates by a multithread system. SOLUTION: The information processor is provided with the TLB 31 which holds address conversion pairs and thread information, a retrieval part 32 which retrieves an address conversion pair of the same virtual address as a virtual address to be converted into a physical address so as to convert the virtual address into the physical address from the TLB 31, a judgment part 34 which judges, when a plurality of address conversion pairs are retrieved by the retrieval part 32, whether or not two or more pieces of thread information among a plurality of pieces of thread information corresponding to the plurality of address conversion pairs are the same and a multi-hit control part 35 which suppresses output of the multi-hit and executes address conversion when it is judged that the pieces of thread information are different by the judgment part 34.
