The invention relates to a process for accessing a storage area of a digital data processing machine (19) in a physical addressing mode the storage arena also being accessible in a virtual addressing mode by means of virtual addresses, each constituted by a logical page number (LPN) and a relative address (SPRA). A first logical page number (i) in question corresponds to a first given physical page number (q), and a second logical page number (i+1) contiguous to the first logical page number (i) in question corresponds to a second physical page number (s), not necessarily contiguous to the first given physical page number (q). The process is comprised of writing, at the address constituted by the first logical page number (i) in question and by a relative address having a first predetermined value, the second physical page number (s).
Process for accessing a storage area of a digital data processing machine (19) in a physical addressing mode, the storage area also being accessible in a virtual addressing mode by means of virtual addresses, each virtual address constituted by a logical page number (LPN) and a relative address (SPRA), wherein a first logical page number (i) in question corresponds to a first given physical page number (q), and a second logical page number (i+1) contiguous to the first logical page number (i) in question corresponds to a second physical page number (s), said second physical page number (s) not necessarily being contiguous to said first given physical page number (q), characterized in that the process comprises writing, at the address constituted by the logical page number (i) in question and by a relative address having a first predetermined value, said second physical page number (s).
Digital data processing machine (19) comprising a storage area accessible by means of virtual addresses, each virtual address constituted by a logical page number (LPN) and a relative address (SPRA), a first logical page number (i) in question corresponding to a given physical page number (q), and a second logical page number (i+1) contiguous to the first logical page number (i) in question corresponding to a third physical page number (s) not necessarily contiguous to said given physical page number (q), said storage area containing, at the address constituted by the first logical page number (i) and by a relative address having a first predetermined value, said third physical page number (s).
