THREE-CHANNEL ASYNCHRONOUS SYSTEM Russian patent published in 1995 - IPC

FIELD: automatics and computer engineering. SUBSTANCE: three-channel asynchronous system comprises three computing units, three units for forming failure signals, generator, three code converters, two trunk switching units, two groups of comparison units, three majority elements, five registers, two groups of registers, three counters, four flip-flops, three groups of AND gates, two groups of OR gates, seven one-shot multivibrators, decoder, three delay elements, fifteen OR gates, eighteen OR gates. The system is characterized in that the possibility of asynchronously performing control and computing algorithms realized according to different versions is provided, rapid tracking of the "pace" and correctness of performance of problems by channels and rejection on this basis of failed channels are carried out, furthermore the possibility of recovery of the state of computing units after failure, the possibility of obtaining reliable solution at two non-crossing failures or failure of one of the the computing units and the operation in a single-channel configuration are provided. EFFECT: enhanced reliability, widened operating capabilities. 6 dwg, 3 tbl
