Abstract
Description
Gegenstand der Erfindung ist die Idee, für die minimale Codierung von Dezimalziffern einen Spezial-4-Feld-Code zu verwenden, der in beiden Umwandlungsrichtungen die Verwendung von einfachen Umcodierschaltungen ermöglicht. Erfindungsgemäß wird diese Vereinfachung mittels eines 4-Feld- Spezial-Codes erreicht, der für die Ziffer 0 4 L-Felder aufweist und für die Ziffern 1 bis 4 je 3 L-Felder und je 1 H-Feld aufweist und für die Ziffern 5 bis 9 je 2 L-Felder und je 2 H-Felder aufweist.The object of the invention is the idea for the minimal Coding decimal digits a special 4-field code too use the use in both conversion directions made possible by simple recoding circuits. According to the invention is this simplification by means of a 4-field Special code reached that has 4 L-fields for the number 0 and for the digits 1 to 4 3 L fields and 1 each H field and for the digits 5 to 9 2 L fields and each has 2 H fields.
Dieser 4-Feld-Spezial-Code ist in Fig. 1 dargestellt. In Fig. 2 ist der normale Dezimal-1-aus-10-Code dargestellt. In Fig. 3 ist die Umcodierschaltung 10 E-4 A dargestellt. In Fig. 4 ist die gegenläufige Umcodierschaltung 4 E-10 A dargestellt, welche Haupt-Gegenstand dieser Patentanmeldung ist.This 4-field special code is shown in Fig. 1. The normal decimal 1 out of 10 code is shown in FIG . In Fig. 3, the Umcodierschaltung 10 is illustrated E-4 A. In Fig. 4, the opposite recoding circuit 4 E-10 A is shown, which is the main subject of this patent application.
Die in Fig. 3 dargestellte Umcodierschaltung 10 E-4 A besteht aus 2 Oder-Schaltungen 21 und 24 mit je 3 Eingängen und 2 Oder-Schaltungen 22 und 23 mit je 4 Eingängen und den zugehörigen Leitungen. Mit dieser Umcodierschaltung 10 E- 4 A werden dezimal-1-aus-10-codierte Dezimalziffern in 4-Feld-codierte Dezimalziffern entsprechend Fig. 1 umgewandelt.The recoding circuit 10 E-4 A shown in Fig. 3 consists of 2 OR circuits 21 and 24 , each with 3 inputs and 2 OR circuits 22 and 23 , each with 4 inputs and the associated lines. With this recoding circuit 10 E-4 A, decimal 1 out of 10 coded decimal digits are converted into 4-field coded decimal digits according to FIG. 1.
Die in Fig. 4 dargestellte Umcodierschaltung 4 E-10 A besteht aus 9 Und-Schaltungen 1 bis 9 mit je 2 Eingängen und der Oder-Schaltung 10 mit 4 Eingängen und der Oder-Schaltung 11 mit 5 Eingängen und 2 Negierschaltungen 12 und 13 und den zugehörigen Leitungen. Mit dieser Codierschaltung 4 E-10 A werden Dezimalziffern von dem in Fig. 1 dargestellten 4-stelligen Spezial-Code in den in Fig. 2 dargestellten Dezimal-1-aus-10-Code umgewandelt. The recoding circuit 4 E-10 A shown in Fig. 4 consists of 9 AND circuits 1 to 9 with 2 inputs each and the OR circuit 10 with 4 inputs and the OR circuit 11 with 5 inputs and 2 negating circuits 12 and 13 and the associated lines. With this coding circuit 4 E-10 A, decimal digits are converted from the 4-digit special code shown in FIG. 1 to the decimal 1 out of 10 code shown in FIG. 2.
Die Wirkungsweise der in Fig. 3 dargestellten Umcodierschaltung 10 E-4 A ergibt sich aus folgender Tabelle: The mode of operation of the recoding circuit 10 E-4 A shown in FIG. 3 results from the following table:
Die Wirkungsweise der in Fig. 4 dargestellten Umcodierschaltung 4 E-10 A ergibt sich aus folgender Tabelle: The operation of the recoding circuit 4 E-10 A shown in Fig. 4 results from the following table:
Die Spiegel-bildliche Ausführungen dieser beiden Codierungen und dieser beiden Umcodierschaltungen sind nicht dargestellt. Auch die B-Ausführungen, bei denen die Ziffer 0 neben der Ziffer 9 angeordnet ist, sind nicht dargestellt.The mirror-image versions of these two codes and these two recoding circuits are not shown. The B versions, in which the number 0 next to the Number 9 is arranged are not shown.
