A fault-tolerant interconnections using LCDMA technique

The need for an efficient and reliable interconnect architecture has been caused by continual technology scaling and increased communication requirements. Using of the logic code division multiple access (LCDMA) and hardware redundancy techniques in order to achieve fault-tolerant interconnection with reduced number of wires, are discussed in this paper. Three different fault-tolerant interconnection approaches are considered: a) adding odd and even parity bit; b) duplication and comparison; and c) triple module redundancy. For BER simulation Matlab tool is used. Taking classical TDMA transmission as a referent one, the amount of BER increase for all three methods is derived. The obtained results show that the increase is within a range from several up to hundred times.
