Translation lookaside buffer control system in computer or virtual memory control scheme

摘要: In a TLB control system of the invention, each entry has bit V' representing validity entry, VN i (i=1, . , n; n is an integer 1 or more) corresponding to next page, and address translation data. A first detecting means detects, for memory access, if correct data stored in accordance with object virtual predetermined fields bits address. second detects single access involves page boundary. replacing replaces detection results means. When replaced by means, replace set unconditionally. The immediately preceding indicated updated. succeeding checked, TLB, checking result.
