| 摘 要： | 提出了一个ＭＰＥＧ２ 视频解码中变长码解码的ＶＬＳＩ设计．采用桶形移位缓冲器并行解变长码、分别进行变长码的长度计算和解码以及将码表分割成多个小码表等新的硬件设计，使得每个周期解一个变长码的码字，保证了ＭＰＥＧ２ ＭＰ＠ ＭＬ的实时解码，并为更复杂的应用提供了扩展的余地．

| Abstract: | AVLSIdesign ofMPEG 2 video variablelength decoding(VLD) w aspresented,w hich ispartof design forMPEG 2 decoding ASICchip. Som especialarchitectureswere introduced forim plem entation of realtim e MPEG 2 MP@ MLdecoding and to decode one variable length coding(VLC) code in one clock period, such as: using a barrelshift buffer for decoding VLCparallel, getting VLClength and the code separately, dividing the code book into sm allcode books, etc. |
