A new technique for applying fault tolerance to modulus replication RNS computations by adding redundancy to the independent computational channels is introduced. This technique provides a low-overhead solution to fault tolerant large inner product computations.

Inspec keywords: error detection; residue number systems; fault tolerant computing; error correction; redundancy

Other keywords: modulus replication RNS computations; fault tolerance; large inner products; redundancy; independent computational channels; low-overhead solution; fault tolerant computation

Subjects: Digital arithmetic methods
