Abstract
Apparatus for comparing a stream of data characters with a predetermined string of test characters has an input device for receiving the stream of data characters and a main processor for generating the predetermined string of test characters. A hardware register receives the predetermined string of test characters from the main processor, and a comparator device compares the stream of data characters with the contents of the register device and generates a response in the event that a portion of the stream is identical to the string of test characters generated by the main processor. A second processor receives the response and sends a report to the main processor.
Claims6
Apparatus for comparing a stream of data characters with a predetermined string of test characters comprising:
- a common bus;
- an input device connected to the common bus for receiving the stream of data characters;
- a first processor connected to the common bus for generating said predetermined string of test characters;
- register means connected to the common bus for receiving the predetermined string of test characters from the first processor;
- comparator means connected to the common bus for comparing the stream of data characters from the input device with the contents of the register means and generating a response in the event that a protion of the stream is identical to said string;
- and
- a second processor connected to the common bus for receiving said response and sending a report to the first processor.
An improved data communications analyzer for comparing a stream of data charaters with a predetermined string of test characters of the type having a processor, an input/output port and a user interface including a display, all interconnected via a common bus, wherein the improvement comprises:
- a register and comparator connected to the common bus for storing the predetermined string and for comparing the stream of data characters with the predetermined string to generate a response in the event a portion of the stream of data characters is identical to the predetermined string;
- and
- a co-processor connected to the common bus for sending a report to the processor when the response is received from the register and comparator.
