摘要：
A variable length decoder that decodes a variable length code to output data including a run and a level, the variable length decoder includes a memory that stores an output format of a run and a level according to a prefix for specifying an area which is generated by dividing a run-level plane based on the run; a extraction circuit that extracts the prefix, run computation data, and level computation data from the variable length code; and an output circuit that accesses the memory based on the prefix and outputs the data based on the run computation data and the level computation data.
