DECODE PROCESSING DEVICE, PROCESSOR, ELECTRONIC DEVICE, DECODE PROCESSING METHOD, AND DECODE PROCESSING PROGRAM

摘要

Provided is a decode processing device capable of reduing the number of cycles required to decode a variable length code as represented by encoding TC or T1s of CAVLC. The decode processing device decodes a variable length code bit stream including a prefix and a suffix following the prefix. The decode processing device includes: a bit-storage control means for holding part of the variable length code bit stream and enabling this holding process operation to be controlled; and a control information and decode address generation control means for generating, based on the prefix of the variable length code bit stream, a decode address used to refer to a decode table, which is necessary for decoding, and generating control information used to update the variable length code bit stream for the bit-storage control means. A process for outputting the decode address is performed simultaneously with a process for updating the variable length code bit stream.
