Description

(54) DEVICE FOR CONVERSION OF BINARY PARTICULAR CODE INTO BINARY

correspond to 2 ° lO, a further 2.

2 IP., 2 10 (B in the given example h. O, 1,2); multi-input single-bit binary adders 4 with multilevel transfer, tires 5 transfer to higher order and tires 6 output numbers in binary code, Succession numbers of adders correspond to a binary number, and from left to right the bits increase (starting from zero). The device operates as follows. Weight input buses 1, 2, 3, divided into tetrads, receive all the digits of the number in binary-decimal code simultaneously. The numeric inputs of adders 4 are supplied with voltages from those input buses whose weights correspond to binary equivalents with a unit in the discharge that matches the adder's serial number (starting from zero), A to the transfer inputs 5 of each adder, transfer moves adder previous low bit.

Thus, on tires 6, a binary number appears at the same time as the least significant bits to the left. The dotted line in the drawing shows an additional connection diagram in the case of a four-bit input binary-decimal number. The total maximum number of adders, i.e. the number of bits LT-numbers in the binary code of the integer part of

P., Y7

where ib is the number of bits of the binary-decimal number.

Subject invention

A device for converting a binary; decimal code into a binary one, containing weighing input buses divided by tetrad and a block of summation, characterized in that, in order to increase fast performance, the block of summation i the transfer input of each of the specified adders / connected to the transfer output of the adder of the previous low-order bit,

.l --f

the numeric inputs of the adder, of the th digit are connected to all input buses, to whose bounds the corresponding binary equipotential ratios with the unit in the i, th digit are.
