I am working on a project "FPGA BASED IMPLEMENTATION OF 2D Disrete Wavelet Transform using Xilinx SYSTEM GENERATOR" and i need to take transpose of a image in it. As there is no block of xilinx is available for transpose of an image so I have developed the algorithm in verilog and import it in BLACK BOX of system generator. I do not want to use simulink for taking tranpose.

When i input the seralize data of 64x64 image to the black box it works fine and give transposed image at the output. But when i put the low pass filter and downsapler after the seralize data of 64x64 image then output transposed image is very blur.
After downsampling output image becomes 32x64.

And if i place filter and downsampler after the seralize data of 64x64 image and replace my black box with the simulik blocks after gatewayout for transpose of a image then the output is good.

I want to ask why the output image is blur when i put filter ,downsampler and blackbox after input stream and what is the solution?

pleaze help...
 

maybe you can start with putting up some code (snippets) up here - why do you think others can help you out without any reference?
