Abstract :
For the purpose of shortening the decoding delay, two VLSI design approaches for the SMU are concurrently studied in this paper. The hybrid approach of trace-back (TB) and trace-forward (TF) in addition to the optimization of the storage method makes the decoding delay greatly reduced. Then we provide a new hybrid approach of register exchange (RE) and TF which has more attractions than the traditional RE in the advantage of its simplification of the corresponding connection scheme.
