Abstract
This paper presents a low-power variable length decoder exploiting the statistics of successive codewords. The decoder employs a small look-up table working as a fixed cache to reduce the number of activations of a variable length code detector where most power is consumed. The power simulation results estimated with Powermill show that 35% energy is reduced on the average compared with the previous low-power scheme
