Segmented one and two level paging address translation system

摘要: An address translation system is provided which has a real storage, virtual storage having "V═R" segment (first segment), second segments to be subjected two-level paging, and page table (third segments) used as corresponding the segments, table, first corresponds memory control unit register microprocessor for translating in into address. By means of microprogram control, function obtaining from number displacement data if represents segment, referring based on does not represent reference result several most significant bits number, remaining data.
