摘要
本文讨论了采用查找表的ＰＶＬＤ的设计和优化，并推导出求ＬＵＴ表项数的具体公式．同时，本文在充分考查了ＦＬＤ和ＶＬＤ的内部联系的基础上，设计了一种定／变长引擎，利用其中的两个桶形移位器，将定长解码器和变长解码器统一在同一电路中，可根据需要解相应长度的定长码或变长码，而且还能处理具有多个Ｈｕｆｆｍａｎ变长码表的情况．本文最后给出了实验结果．
In this paper, we discuss the design and optimization for FVLD, and provide a formula for calcu- late the number of LUT items Based on the relationship between FLD and VLD we design a FVLD engine It uses two barrel shifter,and can decode fixed -length code or variable -length code The engine with the case of several Huffman LUT At last ,we give the experiment results in this paper.
