Abstract: 783,229. Digital electric calculating apparatus. STANDARD TELEPHONES & CABLES Ltd. Nov. 4, 1955, No. 31596/55. Class 106 ( 1 ) Adding and subtracting apparatus comprises a single detector which determines " carry " during addition and " borrow " during subtraction and is not reset between denominations. The various possibilities arising during addition or subtraction of binary digits A and B. taking into account a " carry or "borrow" digit CB from the preceding de. nomination, are as follows: The circuit for determining the new " carry " or " borrow " digit forms the upper portion of the Figure. It is based on the facts that (a) in the case of addition (i) " carry one " does not arise until the first digital place at which A = B = 1 (column IV above), and (ii) must be maintained until A = B = 0 (column V) occurs, and (b), in the case of subtraction, (i) " borrow one " does not arise until the situation " (A = 0) minus (B = 1) " (column III) occurs, and must be maintained until " (A = 1) minus (B = 0) " (column VI). A bi-stable carry/borrow register CB, initially set to zero by a pulse through a buffer G46 is controlled by gates G42 to G45 so as to satisfy these conditions. A = B = 1 during an ADD condition opens gate G43 to change CB to state " 1 ", and A = B = 0 opens gate G42 to return CB to zero, A = 0 and B = 1 change CB to " 1 " during SUBTRACT, and A = 1, B = 0 return it to zero in this case. Clock pulses P are delayed so that CB is not changed over until the end of a digit period. In the lower part of the Figure a different one out of the series of gates G13 to G20 is opened for each possible combination of digits A, B and CB and gives rise to a result signal R1 or RO in accordance with the Table above. Examples of addition and subtraction of both positive and negative numbers, are given in the Specification. Specification 749,440 is referred to.
