A 64-state Viterbi accelerator fabricated in 1.2V, 90nm dual-Vt CMOS technology is described for 2GHz operation and fastest reported 500Mbps data rate (1 Gbps decode for 1/2 rate codes). Novel radix-4 add-compare-select circuits and low-energy traceback register file techniques enable 40mW total power at 1.2V, 2GHz, and scalability to 5mW at 0.7V, 216MHz (for 802.11 a wireless baseband).
