SU692090A1 - Modulus three logical multiplier built around ferrite-ferrite members - Google Patents

Description

Four General elements of the prohibition 5, additional four-interrupt elements of the prohibition 6, 7 and an additional dvutorovy element. Prohibition 8.

On ferrite-ferrite cores (tori) of the prohibition elements are input and output windings (not shown), the input windings are marked with indices 9-29, the outputs of the windings of prohibition elements are marked with indices 30-37, the input buses 38, 39 are multiplied signals, and the bus 40 - clock signal.

The principle of operation of the described modulo logic multiplier 3 is as follows.

This logical element is intended for processing information represented in a three-digit alphabet. In the three-digit alphabet, all the many different types of failures can be divided into three groups:, I1 lO-v 1. jo 2 | $ 24-0 l2-2l il -2}

There is a whole class of three-digit logic devices with asymmetric working conditions, which consists in the loss from. failures of different types differ significantly among themselves.

For example, it is possible to single out the cl.ass devices, for qq qj, qi qg, the losses from the failures of the first second and third groups, respectively .. -.

The functional reliability of three-digit logic devices of this class can be enhanced by ensuring that any one-time malfunction in the device does not appear at the output of the device as a failure belonging to group 1 and 11

Work multiplier modulo three noftcnim on one of the sets. In the first cycle, recording of in-formations into the cores on the windings 10 of prohibition element 1, windings 14, 1b of prohibition element 1, winding 17 of prohibition element 3, winding 18 of element 4 is made. In the next cycle, output 34 of prohibition element 3 reads a negative impulse, and from the output 34 of the prohibition element 4, a positive impulse, and information is recorded only on the winding 24 of the prohibition element 6. In the next clock cycle from the output 36 of the prohibition element

B, a positive pulse is read out and a record is recorded on the winding 29 of the inhibit element 8. In the next clock cycle from the output 37 of the inhibit element 8, a negative pulse is read. The operation of the modulo three modulus on all the other sets of the absence of faults and in the presence of any of the listed one-time faults table. 2 and
