Compression of Multiple-Valued Data Serial Streams by Means of Parallel LFSR Signature Analyzer
It is characteristic of microprocessor systems that, apart from states 1 and 0, also states of high impedance HZ occur in them, among other things, on data and address buses. With regard to this one should take into account the possibility of applying such a state to a signature analyzer. The standard solution here is the application of an appropriate three-state data probe with the unit decoder 3/2 — JK flip-flop  which, at the moment of the HZ state detection, prolongs the previously existing state. Thus, the third state is interrpreted as the state 1 or 0, according to the state which had a tested point before its occurence. Such a solution has been approved by the Hewlett Packard Company and then by other companies in their signature analyzers.
