Method and system for storing and cyclically processing information provided from a large number of information transmission terminals

Claim 1

A method for transferring a portion of a first data word into a second data word said data words provided from information transmission terminals and processed in a central logic control unit, each of said words containing all the information relative to a given terminal, said words being stored in a sequentially accessed circulating memory and sequentially extracted from said memory for temporary storage in a first register during processing so that the interval of time between two successive extractions of the same word is less than the time required for modifying the word through a signalling line of the terminal equipment, said method comprising the steps of: transferring the first word temporarily stored in said first register into a second register connected in parallel with said first register, storing the second word leaving the ciRculating memory in said first register, comparing portions of said first and second data words contained in the first and second registers, transferring a part of the first word into the second word thereby forming a modified second word, the transfer operation occurring after the detection of the second word in the comparing step, and reinserting said modified second word into said circulating memory.

Claim 2

A method for transferring a portion of a first data word into a second data word said data words provided from information transmission terminals and processed in a central logic control unit, each of said words containing all the information relative to a given terminal, said words being stored in a sequentially accessed circulating memory and sequentially extracted from said memory for temporary storage in a first register during processing so that the interval of time between two successive extractions of the same word is less than the time required for modifying the word through a signalling line of the terminal equipment, said method comprising the steps of: transferring the first word temporarily stored in said first register into a second register connected in parallel with said first register, storing the second word leaving the ciRculating memory in said first register, comparing portions of said first and second data words contained in the first and second registers, transferring a part of the first word into the second word thereby forming a modified second word, the transfer operation occurring after the detection of the second word in the comparing step, and reinserting said modified second word into said circulating memory.

Claim 3

A system for cyclically storing and processing information provided from information transmission terminal equipment, said sytem having a sequentially accessed circulating memory for registering words associated with terminal equipment and a parallel register connected to successively receive words from said memory, said parallel register connected to a logical control unit and said parallel register reintroducing words into the memory and inserting new words into the memory from said logic control unit, wherein the improvement of said system comprises: a buffer register connected in parallel with said parallel register for storing words from said logic control unit and said parallel register, and means for comparing portions of a word within said buffer register and portions of a word leaving said parallel register and for providing signals to said logic control unit when said portions are identical, said signals enabling said logic control unit to exchange information between said first and second words.

Claim 4

A system for cyclically storing and processing information provided from information transmission terminal equipment, said sytem having a sequentially accessed circulating memory for registering words associated with terminal equipment and a parallel register connected to successively receive words from said memory, said parallel register connected to a logical control unit and said parallel register reintroducing words into the memory and inserting new words into the memory from said logic control unit, wherein the improvement of said system comprises: a buffer register connected in parallel with said parallel register for storing words from said logic control unit and said parallel register, and means for comparing portions of a word within said buffer register and portions of a word leaving said parallel register and for providing signals to said logic control unit when said portions are identical, said signals enabling said logic control unit to exchange information between said first and second words.
