Abstract
Abstract A method and apparatus for converting characters in a programcontrolled data exchange installation is described. The exchange installation includes at least one common storage unit storing data and programs and processing units inter-operating with the storage unit in a cyclic manner. At least one of the processing units is a program control unit, and at least one is a line termination unit. An additional character handling unit is provided for carrying out character translation. The latter apparatus includes a connecting device regulating the traffic with the common storage, a control section controlling the operations for the various tasks to be performed and a storage section. The latter storage section forms a channel storage, which is divided into separate channel storage areas, each containing a series of channel locations. At the start of a character handling operation initiated by the program control, the channel locations are selectively allocated for the duration of a character handling operation, by entering a corresponding line number of the access line determined by the line number. In order for the character handling unit to receive instructions and data in the channel storage and to transfer message and data from the channel storage it gains cyclic access to specified areas in the common storage which are provided for the reception of instructions, messages and data.

Claim 1
Independent Claim
387 words
In a program controlled data exchange installation having at Least one central store for data and programs for operating said installation and processing units interoperating with said central store in cycles, at least one of said processing units being a program controlled unit and at least one of said processing units being a line connection unit, said central store including a feeder block having a plurality of feeder cells, each of said feeder cells being assigned to a line connected to said line connection unit, said central store including in addition a command block for storing instructions, a record block for storing record information and a transfer block for storing characters, a method for translating data characters comprising the steps of: initiation of a character translation operation by said program control unit, allocation, in reponse to said initiation step, of at least one of a plurality of storage cells in an additional store within a data handling unit for the duration of the character translation operation, by entering therein the number of a line being connected to said line connection unit and accessing said command block in said central store by said data handling unit for the transfer of commands into said additional store in the course of a storage cycle operating as a command cycle. accessing said record block in said central store by said data handling unit for the transfer of record data in the course of a storage cycle operating as a record cycle, accessing said transfer block in said central store for the transfer of data, character by character, in the course of an operating cycle of said central store, which operating cycle is running as a transfer cycle, forming addresses for said command block and said record block by permanently wiring block addresses, forming addresses for storage cells within said command block from a registration of a command counter, forming an address for said transfer block responsive to an allocation of a said line to said storage area in said additional storage and preventing the processing of other cycles until the data transfer has been completed and executing a command cycle in the course of which a command is written in a command register and a record cycle in the course of which a transfer message is written into a transfer register.
Claim 2
Dependent Claim
387 words
In a program controlled data exchange installation having at Least one central store for data and programs for operating said installation and processing units interoperating with said central store in cycles, at least one of said processing units being a program controlled unit and at least one of said processing units being a line connection unit, said central store including a feeder block having a plurality of feeder cells, each of said feeder cells being assigned to a line connected to said line connection unit, said central store including in addition a command block for storing instructions, a record block for storing record information and a transfer block for storing characters, a method for translating data characters comprising the steps of: initiation of a character translation operation by said program control unit, allocation, in reponse to said initiation step, of at least one of a plurality of storage cells in an additional store within a data handling unit for the duration of the character translation operation, by entering therein the number of a line being connected to said line connection unit and accessing said command block in said central store by said data handling unit for the transfer of commands into said additional store in the course of a storage cycle operating as a command cycle. accessing said record block in said central store by said data handling unit for the transfer of record data in the course of a storage cycle operating as a record cycle, accessing said transfer block in said central store for the transfer of data, character by character, in the course of an operating cycle of said central store, which operating cycle is running as a transfer cycle, forming addresses for said command block and said record block by permanently wiring block addresses, forming addresses for storage cells within said command block from a registration of a command counter, forming an address for said transfer block responsive to an allocation of a said line to said storage area in said additional storage and preventing the processing of other cycles until the data transfer has been completed and executing a command cycle in the course of which a command is written in a command register and a record cycle in the course of which a transfer message is written into a transfer register.
Claim 3
Dependent Claim
74 words
The method defined in claim 1 comprising the further steps of: communicating the idle condition of said storage cells in said additional store to said central store, determining an idle additional storage cell and responsive to the determination of said idle additional storage cell entering the number of said line being connected to said line connection unit and the instructions required for execution of a character translation operation into said idle additional storage cell.
Claim 4
Dependent Claim
57 words
The method defined in claim 1 comprising the further steps of: searching through said additional store in order to locate an idle storage cell and entering during an instruction cycle, into said idle storage cell, so located, the number of said line being connected to said line connection unit and the instructions for a character translation operation.
Claim 5
Dependent Claim
