摘要： Provided are an apparatus for decoding a minimum memory access-based context adaptive variable length code (CAVLC) of the moving picture compression standard, H.264, and a table search method for decoding a context adaptive variable length code using the same. The apparatus for decoding a context adaptive variable length code may be useful to improve an overall decoding speed since the repeated memory accesses may be reduced to 2 cycles of memory accesses by reconstructing a context adaptive variable length code table of first decoding information (TrailingOnes) and second decoding information (TotalCoefficient) into 2-step tables and storing the reconstructed 2-step tables in advance and performing a table search to decode the first decoding information and the second decoding information, by using the information stored in the 2-step tables, depending on whether the remaining bits except for the number of leading zero are present in the inputted bit stream.
摘要翻译：提供了一种用于解码运动图像压缩标准H.264的最小存储器访问上下文自适应可变长度码（CAVLC）的装置，以及用于使用其进行上下文自适应可变长度码的解码的表搜索方法。用于对上下文自适应可变长度码进行解码的装置对于提高整体解码速度可能是有用的，因为通过重建第一解码信息（TrailingOnes）的上下文自适应可变长度码表，可以将重复的存储器访问减少到2个周期的存储器访问，第二解码信息（TotalCoefficient）到2步表中，并且通过使用存储在2步表中的信息，预先存储重建的两步表并执行表搜索以解码第一解码信息和第二解码信息，取决于在输入的比特流中是否存在除了前导零的数目之外的剩余比特。

摘要： Provided is an H.264 Context Adaptive Variable Length Coding (CAVLC) decoding method based on an Application-Specific Instruction-set Processor (ASIP). The H.264 CAVLC decoding method includes determining a plurality of comparison bit strings on the basis of a table of a decoding coefficient, storing lengths of the comparison bit strings in a first register, storing code values of the comparison bit strings in a second register, comparing an input bit stream with the comparison bit strings based on the lengths and code values of the comparison bit strings, and determining value of the decoding coefficient according to a result of comparison between the input bit stream and the comparison bit strings. The method extracts a decoding coefficient using a register in an ASIP without accessing a memory and prevents a reduction in speed caused by memory access, thereby increasing the decoding speed of an H.264 decoder.
