Abstract

The translator converts binary coded characters to their decimal digit equivalents. One bistable magnetic core is employed for each decimal digit. Input lines corresponding to the number of bits in the input code character are threaded through the cores in a predetermined pattern to effect translation. The input lines are,arranged with respect to each core so that those representing bit positions containing 1's in the corresponding input character are coupled in the reset direction, while those representing positions containing 0's are coupled in the set direction. A bias line is coupled to each core, except the one representing digit 7, with two turns in the reset direction.

Magnetic Core Translator

The translator converts binary coded characters to their decimal digit equivalents. One bistable magnetic core is employed for each decimal digit. Input lines corresponding to the number of bits in the input code character are threaded through the cores in a predetermined pattern to effect translation. The input lines are,arranged with respect to each core so that those representing bit positions containing 1's in the corresponding input character are coupled in the reset direction, while those representing positions containing 0's are coupled in the set direction. A bias line is coupled to each core, except the one representing digit 7, with two turns in the reset direction.

The input drivers for the several input lines are controlled by the character register, where a character to be translated is placed.

A driver is activated only if a 0 is stored in the corresponding position of the character register. All drivers produce half-select current. With this arrangement, the core representing the digit corresponding to the input code character receives input drive currents in the set direction only. Other cores receive input drive current in both directions. The summation of currents, including the bias current, is such that the core representing the digit corresponding to the input character receives a net single half-select current in the set direction, while all others receive one or more half-select currents in the reset direction.
