Abstract
Abstract A program controlled data processing installation which is particularly useful with telecommunication exchange switching is described. The system includes an information processing mechanism controlled by a program control mechanism. The data processing installation is of the type which is capable of executing branching operations upon receipt of a jump command. The installation includes a jump switching network which forms and delivers the jump commands to the program control mechanism. In the jump switching network, internal unconditional jump information and conditional jump information is processed in the course of the execution of a program along with external jump information. The jump switching network includes a plurality of coupling members which are individually associated with the particular jump commands to be executed.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
193 words
In a program controlled data processing installation for controlling telecommunication exchange systems having a program control means which operates an information processing means for executing programs including branching operations which are indicated by jump commands, the improvement comprising: jump switching circuit means including a plurality of coupling circuits for forming and communicating instruction signals to said program control means, said instruction signals indicating one of the execution and non-execution of a jump command, said instruction signals being formed from internal and external jump information coupled to said jump switching circuit means, first input means from said information processing means to said jump switching circuit means over which jump information processed internally and dependent on said processing in the course of the execution of a program is routed, second input means from said program control means to said jump switching circuit means over which internal unconditional jump information is routed, and third input means from external lines to said jump switching circuit means, said external lines being connected to said systems controlled by said data processing installation, said external lines and said third input means routing external jump information to said data processing installation.

Claim 3
Dependent Claim
71 words
The program controlled data processing installation defined in claim 1, wherein said coupling circuits in said jump switching circuit means are gating elements individually assigned to shift commands to be executed, and further comprising: testing means for testing said gating elements after the appearance of command words for branching instructions during the processing of the program in order to supply connection results representing jump commands which determine the execution of jumps.
Claim 4
Dependent Claim
139 words
The program controlled data processing installation defined in claim 2, wherein each of said gating elements is constituted by a pair of AND gates, each said AND gate having three inputs, a further comprising: address line means, one of which is assigned to each gate pair, transmission line means for transmitting internal and external jump information and, NOT gate means adapted to be switched before the inputs of said AND gates, the two first inputs of each said AND gate pair being jointly connected to one of said addresss lines, two second inputs of each said AND gate pair being connected jointly to a transmission line and switching means for switching one of said NOT gate means before said second inputs, third input means of said AND gates being connected to said NOT gates and to a control line.
Claim 5
Dependent Claim
59 words
The program controlled data processing installation defined in claim 3, further comprising: address decoder means and command register means in said program control means, and wherein said address lines assigned to addresses of pairs of said AND gates are connected to said address decoder, the inputs of said address decoder being connected to a portion of said command register.
Claim 6
Dependent Claim
30 words
The program controlled data processing installation defined in claim 4, wherein the address of a pair of said AND gates is represented by the address portion of a command word.
Claim 7
Dependent Claim
99 words
The program controlled data processing installation defined in claim 4, further comprising: operation register means in said information processing means and means in said information processing means for generating an information signal corresponding to the addresses of said pairs of AND gates, and wherein said address decoder means is additionally connected to said operations Register and the address of a pair of AND gate means considered in making a connection of jump information is represented by the information established within the course of the processing of the program and is forwarded to said address decoder over said operation register.
Claim 8
Dependent Claim
47 words
The program controlled data processing installation defined in claim 4, further comprising: operation decoder means adapted to receive the operation portion of a command word from said program control mechanism and control lines means connecting said operation decoder means to said third inputs of said AND gates.
