Abstract

1,148,472. Data processors. INTERNATIONAL BUSINESS MACHINES CORP. 4 April, 1966 [5 April, 1965], No. 37413/68. Divided out of 1,148,471. Heading G4A. Data processing apparatus includes a first and a second operation register for storing the operation code of an instruction, in which the operation code in the second register is set from the first register, in which the operation code in the first register is replaced by the operation code of the next instruction before the execution of the current instruction is completed and in which execution of the current instruction is initially controlled by the first register and subsequently controlled by the second register.
