Abstract
A voter subsystem for a multiple node fault tolerant system having an upper medial value sorter for sorting a plurality of received values to generate an upper medial value and a lower medial value sorter for sorting the same plurality of received values to generate a lower medial value. An averaging circuit adds the upper and lower medial values then divides by two to generate a voted value. A deviance checker checks each of the plurality of received values against the voted value to generate a deviance error for each received value which differed from the voted value by a predetermied amount. A loader loads the plurality of received values into the upper and lower medial value sorters and the deviance checker bit-by-bit, starting from the most significant bit positions through the least significant bit positions. The upper and lower medial value sorters and deviance checker process the received values on-the-fly in the order they are received.
