ABSTRACT:
A data processing system includes central storage where access to data is by central storage addresses. Instructions normally include a logical or virtual address which is translated to a real central storage address using dynamic address translation (DAT) with or without an access register (AR) translation mechanism. When in AR mode, and with DAT on, addressing of instructions or data in central storage can be effected by specifying real central storage addresses and eliminate the DAT and AR translating process.
