Abstract
Abstract A program controlled data processing installation particularly useful with telephone exchange switching is described. The system includes an information processing mechanism which is controlled by a program control mechanism. The processing mechanism receives binary signals which are then processed and a determination of their ultimate utilization made. The system also selects the binary signals which will be operated on from among several available and requiring operation.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
153 words
In a program controlled data processing system for a telecommunication exchange installation having a program control means with associated memory and information processing means controlled by said program control means, said information processing means including at least one operation register for receiving from several binary signals one of information to be processed and processed information the improvement comprising: selection circuit means in said information processing means for making a selection from the binary characters of the information to be processed and the processed information in said operation register for determining the utilization of said information in a predetermined manner, distribution line means for connecting the results of the operation of said selection circuit means to other portions of said information processing means, means connecting the outputs of said selection circuit means to said distribution line means and means connecting the inputs of said selection circuit means to the outputs of said operation register.
Claim 2
Dependent Claim
153 words
In a program controlled data processing system for a telecommunication exchange installation having a program control means with associated memory and information processing means controlled by said program control means, said information processing means including at least one operation register for receiving from several binary signals one of information to be processed and processed information the improvement comprising: selection circuit means in said information processing means for making a selection from the binary characters of the information to be processed and the processed information in said operation register for determining the utilization of said information in a predetermined manner, distribution line means for connecting the results of the operation of said selection circuit means to other portions of said information processing means, means connecting the outputs of said selection circuit means to said distribution line means and means connecting the inputs of said selection circuit means to the outputs of said operation register.
Claim 3
Dependent Claim
58 words
The program controlled data processing system defined in claim 1 wherein said selection circuit means includes a plurality of series connected switching stages, each said switching stage being associated with binary characters belonging to a predetermined piece of information thereby determining a sequence in which binary characters belonging to a piece of information are considered in the selection.
Claim 4
Dependent Claim
44 words
The program controlled data processing system defined in claim 2 wherein said switching stages include connecting means for interchanging the sequence of said switching stages in the series configuration so that the starting location of the sequence can be changed for each selection operation.
Claim 5
Dependent Claim
30 words
The program controlled data processing system defined in claim 3, wherein each said switching stage comprises means for selecting a single binary character when a given switching stage is selected.
Claim 6
Dependent Claim
86 words
The program controlled data processing system defined in claim 2, further comprising: an additional operation register in said information processing means having inputs connected to at least one of said program memory or external means controlled by said system, said additional register being adapted to receive a nuMber of signals corresponding to the number of signals received by said operation register whereby the starting point of the sequence to be considered in the selection is determined utilizing the binary signal different from the remaining binary signals.
Claim 7
Dependent Claim
92 words
The program controlled data processing system defined in claim 5, wherein said selection circuit means includes a plurality of switching stages individually assigned to binary signals to be processed, a cascade circuit of unidirectional conduction means contained individually in said switching stages, and further comprising: means for connecting each switching stage to a potential corresponding to the binary signal in question, said switching stages being coupled through interconnection of contact means, only those contact means being non-conducting to which the binary signal determined as the starting point of the sequence is assigned.
Claim 8
Dependent Claim
38 words
The program controlled data processing system defined in claim 1, wherein said information to be processed comprises signals from a plurality of simultaneously requesting telephone subscriber circuits, said selection means determining which subscriber connection is to be processed.
