The multi-level LUT method for VLD is a fast, memory efficient method and is widely implemented in digital video and image decoders. This paper discusses the design and optimization for multi-level LUT and its state-machine in details, provides a formula for calculating the items of LUT and FSM states, and then proves the algorithm with an experiment of MPEG1. According to the result of this paper, the items in LUT can be fully saved in hardware design.
