Abstract
A dynamic multiple comparison device for real time monitoring of changes in incoming digital words streams. The device includes a memory (12) having N memory cells, a comparison section (13, 11, BD1, BD3, BA1) for making a series of N comparisons, a selection section (RC) for selecting after each N comparison, a digital word, a first writing section (14, BD2, W) for writing the selected N digital words, a reading section (11, BA1, BA2, CL, R) for reading the stored digital words, and a control section (17, LC) for controlling the cyclic operation of the device. The device has applications in nuclear power plant control and monitoring.
Claims13
A dynamic multiple comparison device to monitor, in real time, changes in an incoming digital word stream, comprising:
- memory means having N memory cells for storing respectively N digital words previously selected from said incoming digital word stream, N being a predetermined whole number,
- comparison means for effecting a series of N comparisons respectively between N incoming digital words and said N stored digital words of a same rank,
- selection means for selecting, following each of the N comparisons, a digital word among two compared digital words as a function of a predetermined comparison condition to obtain N selected digital words,
- first writing means for writing said N selected digital words respectively to said N memory cells of said memory means,
- addressing means for addressing said stored digital words in said memory means,
- control means for controlling a cyclical operation of the device to process said incoming digital word stream by successive series of N comparisons each, and
- second writing means for writing, episodically or cyclically, initialization digital words to said memory cells of said memory means.
