13. A computer system as recited in claim 12, wherein said translator comprises: means for dividing a virtual address signal into a virtual page number signal and a virtual page offset signal; translation means for receiving said page number signal, translating said virtual page number signal into a physical page number and a domain number and a permission, and issuing a physical page number signal and said domain number signal and a permission signal if said virtual page number signal can be translated, but issuing a translation fault signal forming a first part of said first fault indication if said virtual page number cannot be translated; permission control logic for receiving said permission signal and said access type signal, determining if an access type corresponding to said access type signal is allowed by said permission signal, and issuing a permission fault signal if said access type signal is not allowed, said permission fault signal forming a second part of said first fault indication; and means for combining said physical page number signal and said page offset signal to produce said physical address signal.
14. A computer system as recited in claim 13, wherein said translation means includes: a translation look-aside buffer for receiving said virtual page number signal, comparing said virtual page number signal to a page number table of said translation look-aside buffer, and if said virtual page number signal corresponds to a page number entry in said page number table, then issuing said physical page number signal and said domain number signal and said permission signal, but if said virtual page number signal does not correspond to a page number entry in said page number table, then issuing a no-match signal; and translation table look-up logic for receiving said no-match signal and said virtual page number signal, determining if a valid page number entry exists in said memory for said virtual page number signal, and filling an entry register of said page number table with said valid page number entry if said valid page number entry exists, but issuing said translation fault signal if said valid page number entry does not exist.
