DIGITAL CIRCUIT USING MEMORY FOR MONITORING SIGNALS FOR OCCURRENCES OF PREDEFINED BREAKPOINT CONDITIONS

摘要

Stop unit includes a digital signal memory circuit (30, 50) for monitoring the (B _1, ..., B _n, C _1, ..., C _m) with respect to the occurrence of any of the plurality of predefined conditions It includes. The memory circuit has a memory cell array (34, 53), one cell selected from the group consisting of include and the cells (each cell storing data (I _i, K _lm) for determining the value of interest, stop condition) is the signal bit in response to the various combinations it can be read out. The accessed data values ​​are used for operation of the circuit 20 for generating the signal to be monitored as a stop signal to stop or reset. Alternative embodiment multiple of the memory circuit (41, 42; 60, 61) for monitoring the set of distinct signal bits for the different interest conditions the data value may have a corresponding access is a logic gate (43) in order to generate a bond or stop signal (K _ij, L _m) by it can be used as an input to the memory circuit 62 of the second stage.
