DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention relates generally to signal processing. More particularly, the invention relates to the monitoring in real time of changes of a plurality of available signals in the form of an uninterrupted flow of digital words.
BACKGROUND OF THE INVENTION
The development of techniques gives rise to ever increasing complexity of the systems. In a complex system such as a control and monitoring system in a nuclear power plant, the number of signals apt to malfunction or requiring adjustments in real time is always very great. Security requirements often impose real time constraints on signal processing, and there exists a real need for monitoring devices capable of following the changes in a plurality of signals. With such monitoring devices, it becomes possible to detect certain particular events in the signals so as very rapidly to take suitable measures or to actuate alarms. In another field, that of high fidelity audit signal transmission systems such as those produced and processed in recording studios, radio and television stages and control rooms, or concert halls, it is important to be able to monitor signals in real time, essentially to avoid distortions due to saturation and to adjust gain optimally.
SUMMARY OF THE INVENTION
The present invention therefore has for its object to provide dynamic multiple comparison devices permitting monitoring simultaneously a large number of signals supplied in the form of digital words, and this in real time.
Another object of the invention is to provide dynamic multiple comparison devices which, by their design, will be available in the form of integrated circuits, so as to be easily integrated into systems and this at low cost and with maximum guarantee of reliability.
To this end, the invention relates to a dynamic multiple comparison device to monitor in real time changes in a stream of incoming digital words, characterized in that it comprises memory means having N memory cells to memorize respectively N previously selected digital words from the stream of incoming digital words, N being a predetermined whole number, comparison means to effect a series of N comparisons respectively between N incoming digital words and the N memorized digital words, upon each comparison an incoming digital word being compared with a memorized digital word of the same rank, selection means to select after each of the N comparisons a digital word from among the two compared digital words and this as a function of a predetermined comparison condition and to obtain thereby N selected digital words, first writing means to write the N selected digital words respectively in the N memory cells of the memory means, reading means to read the memorized digital words in the memory means, and control means to control a cyclic operation of the device and thereby to process all of the stream of incoming digital words by means of a plurality of successive series of N comparisons each.
According to another characteristic, the device according to the invention also comprises second writing means to write episodically or cyclically initialization digital words in the memory cells of the memory means.
Still another object of the invention is to provide dynamic multiple comparison devices easily integrable into professional systems for processing high fidelity audio signals.
To this end, a dynamic multiple comparison device included in a professional switching and bidirectional transmission system with time multiplexing of high fidelity audio-digital signals and audio-analog signals is characterized in that it comprises means to permit a display of the memorized digital words on a screen of a microprocessor included also in the system and this in a plurality of control blocks provided on said screen so as to permit the user to monitor in real time the change of various parameters of a plurality of signals transmitted in the system and to control in real time modifications and adaptations of configuration of the system. Preferably, the device also comprises add
