2) shift-add operation
移位-加操作
1.
A simple shift-add operation is used to substitute for the multiplier with complicated architecture operating on floating-point, so that the 9/7 discrete wavelet transform in JPEG2000 is implemented through fixed-point computing.
基于实数的二进制表示法,把CDF(Cohen,DaubechiesandFeauveau)9/7双正交小波基的提升系数化为二进制,采用简单的移位-加操作代替结构复杂的浮点乘法器,从而实现了JPEG2000中9/7离散小波变换的定点计算。
