DEVICE FOR SEARCH FOR FAULTS OCCURRING INTERMITTENTLY IN MICROPROCESSING SYSTEMS Russian patent published in 1995 - IPC

FIELD: computer engineering. SUBSTANCE: device for search for faults occurring intermittently in microprocessing systems has decoder 4, multiplexer 5 of main lines, binary counter 15, unit 16 of standard buffer storage, address multiplexer 24, triggering register 27, data multiplexer 26, first flip-flop 17, short pulse former 38, selector 6, control register 7, first comparison circuit 28, pulse subtracting counter 30, first former 36 of recording signal. Novelty of device lies in presence of buffer storage unit 23 of present cycle, second comparison circuit 29, address register 25, seven AND gates 8-14, three OR gates 31-33, second, third, fourth, fifth and sixth flip-flops 18-22, second former 37 of recording signal, second former 35 of reading signal. EFFECT: increased productivity of search for faults occurring intermittently. 1 dwg
