Abstract
Abstract A process and apparatus are described for operating a program controlled data exchange system having at least one central memory constructed in the form of a multistorage unit containing programs necessary for the operation of the system. The system also has processing units which operate cyclically with the central memory over a memory input-output control according to the principles of demand and call-back. The reception, distribution and selection of operation demands sent by the processing units take place at a central location over an operation demand control in which an operation distribution register contains a specific association given through address and contents between storable information about the priority of an operation and the information about the processing unit carrying out an operation. For the targeted distribution of operation demands the information about the priority of an operation to be carried out serves as an internal register address for a seeking operation in the operation distribution register. The aforementioned seeking process results in information being available for the identification of the processing unit carrying out this operation. For the selection of operation demands the processing units initiate an associative seeking process, after the completion of an operation. During the seeking process, the entire contents of the operation distribution register are available for a comparison process for which comparison the information identifying the demanding processing unit serves as comparison criteria. Resulting from this comparison, the information stored for this processing unit in the operation demand control about the highest priority of an operation is available.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
200 words
Apparatus for operating a program controlled data exchange system having at least one central memory constructed as a multistorage unit and containing the programs necessary for the operation of the system and having a plurality of processing units which alternately and cyclically operate with said central memory over a memory input-output control, comprising: operation demand control means for reception, distribution and selection of operation demands sent by said processing units, operation distribution register in said operation demand control means containing information as to a specific association between the priority of each operation and the identity of the one of said processing units performing each said operation, said operation distribution register performing a seeking process using said priority information as an internal register address, means responsive to the result of said seeking process for identifying the one of said processing units carrying out each said operation, means for performing an associative seeking process comparing the entire contents of said operation distribution register with the information identifying the demanding processing unit and means utilizing the result of said comparison for producing information, stored for the demanding processing unit in said operation demand control means, concerning the highest priority value for an operation.
Claim 2
Dependent Claim
200 words
Apparatus for operating a program controlled data exchange system having at least one central memory constructed as a multistorage unit and containing the programs necessary for the operation of the system and having a plurality of processing units which alternately and cyclically operate with said central memory over a memory input-output control, comprising: operation demand control means for reception, distribution and selection of operation demands sent by said processing units, operation distribution register in said operation demand control means containing information as to a specific association between the priority of each operation and the identity of the one of said processing units performing each said operation, said operation distribution register performing a seeking process using said priority information as an internal register address, means responsive to the result of said seeking process for identifying the one of said processing units carrying out each said operation, means for performing an associative seeking process comparing the entire contents of said operation distribution register with the information identifying the demanding processing unit and means utilizing the result of said comparison for producing information, stored for the demanding processing unit in said operation demand control means, concerning the highest priority value for an operation.
Claim 3
Independent Claim
192 words
A method for the operation of a program controlled data exchange system having at least one central memory constructed as a multi storage unit and containing programs necessary for the operation of said exchange system, Said exchange system having a plurality of processing units which alternately and cyclicly operate with said central memory over a memory input-output control according to the principle of demand and call-back, comprising the steps of: distributing and selecting operation demands sent from said processing units in a central location utilizing, respectively, a common operation distribution register and an operation demand register, placing information in said operation distribution register regarding a specific association between a first unit of information concerning the priority of a given operation demand and a second unit of information regarding the processing unit wherein the said given operation demand shall be performed, storing said first unit of information in said operation demand register, decoding said first unit of information for addressing said operation distribution register and said operation demand register, generating, from a unit of control information, instruction signals for the individual functions of the operation distribution register and the said operation demand register.
Claim 4
Independent Claim
192 words
A method for the operation of a program controlled data exchange system having at least one central memory constructed as a multi storage unit and containing programs necessary for the operation of said exchange system, Said exchange system having a plurality of processing units which alternately and cyclicly operate with said central memory over a memory input-output control according to the principle of demand and call-back, comprising the steps of: distributing and selecting operation demands sent from said processing units in a central location utilizing, respectively, a common operation distribution register and an operation demand register, placing information in said operation distribution register regarding a specific association between a first unit of information concerning the priority of a given operation demand and a second unit of information regarding the processing unit wherein the said given operation demand shall be performed, storing said first unit of information in said operation demand register, decoding said first unit of information for addressing said operation distribution register and said operation demand register, generating, from a unit of control information, instruction signals for the individual functions of the operation distribution register and the said operation demand register.
Claim 5
Dependent Claim
75 words
The method defined in claim 2 comprising the further steps of: addressing with said first unit of information a particular location in said operation distribution register, communicating said first unit of information, as well, directly to an address output register, storing said first unit of information in said operation demand register and storing said second unit of information, which was held in said address portion of said operation distribution register, in a word output register.
Claim 6
Dependent Claim
111 words
The method defined in claim 2 comprising the further steps of: initiating an associative search process in said operation distribution register using said first unit of information, transferring the contents of the location in said operation distribution register reached through said process sequentially to a comparator means, said contents of said operation distribution register being said second unit of information, coupling said second unit of information, as well, to a word output register, comparing the result of said comparator means with the contents of said operation demand register and transferring a positive comparison result, after a priority selection in a priority selector circuit, to an address output register in encoded form.
