Abstract
Techniques, apparatus and systems are described for performing variable length decoding. In one aspect, a variable length decoding apparatus includes a first computation unit to determine whether a symbol corresponding to an input data is included in an upper group or a lower group of a variable length code tree. Responsive to the determination, when the symbol corresponding to the input data is included in the lower group, the first computation unit detects look-up table information corresponding to a subgroup that includes the symbol corresponding to the input data within the lower group that includes multiple subgroups. The variable length decoding apparatus includes a second computation unit to detect the symbol corresponding to the input data by searching a look-up table corresponding to the look-up table information when the look-up table information is received from the first computation unit.
