method for random access of a memory area of a digital verarbeitungsvorrichtung in a physical adressierungsmodus and a virtual adressierungsmodus and device implementing the method

摘要

Where a logical page number corresponds to a physical page number the contiguous logical page number will not necessarily correspond to the contiguous physical page number. The difficulty is overcome by writing the correct next physical page number into the first logical page address and also the first given relative address. A machine (19) using this principle has twelve pointers (22) linked to pages and to physical and virtual addresses (Ar1-6, Av1-6)
