Abstract--This paper presents a reconfigurable viterbi fabric
with efficient track-back unit in a system on chip device. The
proposed reconfigurable fabric can support Viterbi
implementations with constraint lengths ranging from 3 to 9,
and code rates in the range 1/2-1/3. Our results illustrate that
