Abstract

Abstract An arrangement for verifying the content of an output buffer in a system including a first register which, during an initial memory word search, is used to compare with a second register to find a proper translation memory word. During the verify mode, the first register, via a verify bus, takes data loaded to the output buffer and compares the content with the data in the second register.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 93 words
In a communication system wherein a first register is used to find a proper memory word by comparing its contents with a second register, and when the proper memory word is found and is loaded from said second register to an output buffer, a method for verifying the content of said output buffer comprising the steps of: a. coupling the content of said output buffer into said first register and storing the same therein; and b. comparing the content of said first register with the content of said second register for a match.
Claim 2
Dependent Claim 93 words
In a communication system wherein a first register is used to find a proper memory word by comparing its contents with a second register, and when the proper memory word is found and is loaded from said second register to an output buffer, a method for verifying the content of said output buffer comprising the steps of: a. coupling the content of said output buffer into said first register and storing the same therein; and b. comparing the content of said first register with the content of said second register for a match.
Claim 3
Dependent Claim 76 words
In the communication system of claim 1, wherein selected bits of the proper memory word are loaded from said second register to said output buffer, said method further including the steps of: a. clearing said first register; b. coupling the selected bits in said output buffer into said first register and storing the same therein; and c. comparing said selected bits in said first register with the selected bits in said second register for a match.
Claim 4
Dependent Claim 186 words
In a communication system including a call data store for receiving and storing information data and a memory for storing a plurality of translation memory words, certain ones of said translation memory words being associated with and providing a proper translation memory word for said information data, an arrangement comprising a first register into which said information data from said call data store is temporarily stored; a second register into which memory words from said memory are temporarily stored; comparator means for comparing a memory word read from said memory and stored in said second register with said information data read from said call data store and stored in said first register, an output buffer into which said translation memory word is stored when a comparison between a translation memory word and said information data is found; a verify bus for coupling said translation memory word coupled to and stored in said output buffer into said first register for comparison by said comparator means with said translation memory word stored in said second register, to thereby verify the received and stored content of said output buffer.
Claim 5
Dependent Claim 186 words
In a communication system including a call data store for receiving and storing information data and a memory for storing a plurality of translation memory words, certain ones of said translation memory words being associated with and providing a proper translation memory word for said information data, an arrangement comprising a first register into which said information data from said call data store is temporarily stored; a second register into which memory words from said memory are temporarily stored; comparator means for comparing a memory word read from said memory and stored in said second register with said information data read from said call data store and stored in said first register, an output buffer into which said translation memory word is stored when a comparison between a translation memory word and said information data is found; a verify bus for coupling said translation memory word coupled to and stored in said output buffer into said first register for comparison by said comparator means with said translation memory word stored in said second register, to thereby verify the received and stored content of said output buffer.
Claim 6
Dependent Claim 180 words
In a communication system including a call data store for receiving and storing information data, a memory for storing a plurality of translation memory words, certain ones of said translation memory words being associated with and providing a proper translation memory word for said information data, comparator means for comparing said translation words with said information data during an initial memory word search to locate the proper translation word, and an output buffer into which the translation word is stored when a comparison between a translation memory word and the information data is found, an arrangement comprising a first register into which said memory words are read during said initial memory word search for the proper translation memory word, and a second register for providing the dual function of storing said information data used to compare with said memory words stored in said first register and for taking and storing data loaded into said output buffer from said first register for comparison with the content of said first register to verify the received and stored content of said output buffer.
Claim 7
Dependent Claim 180 words
In a communication system including a call data store for receiving and storing information data, a memory for storing a plurality of translation memory words, certain ones of said translation memory words being associated with and providing a proper translation memory word for said information data, comparator means for comparing said translation words with said information data during an initial memory word search to locate the proper translation word, and an output buffer into which the translation word is stored when a comparison between a translation memory word and the information data is found, an arrangement comprising a first register into which said memory words are read during said initial memory word search for the proper translation memory word, and a second register for providing the dual function of storing said information data used to compare with said memory words stored in said first register and for taking and storing data loaded into said output buffer from said first register for comparison with the content of said first register to verify the received and stored content of said output buffer.
