咨询其中图像FFT ip核配置问题

最近在用sysgen做图像处理,对图像进行傅里叶变化,新手,首先先不知道错在了哪里?sysgen程序如图所示
首先在m文件中做图像数据的生成:
s1=imread('jupiter.jpg');
s2=imresize(s1,[256,256]);
ss1=reshape(s2',1,65536);
a=[double(0:65535)' double(ss1)'];
as=[a(:,1),a(:,2)/255];
a=as;
b=double([[0:65535]',zeros(65536,1)]);
设置FFT ip核参数:
transform length:512 Target clock frequency:250Mhz Phase factor width:16
Unscaled Convergent rounding Natural order Number of stages using Block RAM:4

图像总是与Matlab得到的不同

由于刚开始学习sysgen,不知该如何学习,希望大家指导建议,大家有没有可以推荐的相关书籍、专业论坛或者例子,谢谢!
