ABSTRACT:
A high-speed variable length decoding apparatus independently generates a run-level symbol and decodes the run-level symbol, to thereby variable length decode the variable length coded data at high frequency for signal processing. The variable length decoding apparatus includes a storage and output portion for storing the variable length coded data and outputting the stored variable length coded data by a predetermined data amount in response to a data storage state signal, a run-level table for outputting a run-level symbol which is determined by the data output from the storage and output portion, a memory for storing and outputting the run-level symbol output from the run-level table, in a first-in-first-out manner, and generating the signal indicating a data storage state of its own, and a run-level decoder for run-level decoding the run-level symbol output from the memory.
