N2 - An Ultra-high-speed (higher than 60Mbps) Viterbi decoder VLSIC with coding rates from one-half to fifteen-sixteenth and a constraint length of seven for forward error correction (FEC) has been developed using 0.8-μm semi-custom CMOS LSIC technology. To reduce the power consumption of the one-chip high-coding-rate Viterbi decoder, a newly developed universal-coding-rate scarce-state-transition (SST) Viterbi decoding scheme and low-power-consumption burst-mode-selection (BMS) path memory have been employed. In addition, a new maximum-likelihood-decision (MLD) circuit of the SST Viterbi decoder has been developed to reduce the path memory length without coding-gain degradation. The developed Viterbi decoder VLSIC achieves a maximum data rate of 60Mbps with a power consumption of 2.5W and achieves near theoretical net coding-gain performance for various coding rates.
