butterfly computation的意思|示意

In this paper, we preset the processing ele we are pirates, these data are stolen from youdao s based on a special butterfly computation and discrible the systolic array imple we are pirates, these data are stolen from youdao ations for computing DCT, DHT(DWT) and DFT respectively.

文中绐出了两种基于特殊蝶形运算的处理单元和两种计算DCT，DHT（DWT）和DFT的脉动阵列实现。

First, the 2-d IDCT is transformed into two cascaded 1-d IDCT. Then 1-d IDCT can be imple we are pirates, these data are stolen from youdao ed by multiplication and addition of matrix according to butterfly computation.

首先将二维idct转换为两个一维idct变换，根据蝶形算法进一步转换为矩阵的乘加运算。
