Some Aspects about the Efficiency of Bit Voters Implementation

Voting is a fundamental operation in the realization of ultrareliable systems that are based on multi-channel computations. When data to be voted on are generated at a high rate, the voter must be able to keep up with the processing speed. The actual voting delay might not be critical but the voter throughput must match or exceed the input data rate. Designs of hardware voters are presentedthat can be easily pipelined to accommodate extremely high data rates. Design strategies for bit voters are described. Examples of resultant designs are given and each design is evaluated with respectto cost and performance.
