Hi!
I am coding the module that calculate SAD between current and reference block using 2D-Tree Architecture. It includes 2 module: module calculation+module control (I think so)
About module calculation SAD, I formed it as following:
+ Input includes 32bit for 4pixel current and reference.
+ Output is SAD minnimum.

But the module control that operate mapping strategy data pixel to feed current and reference pixel to above module calculation, I do not know exactly how is it?
Pls give me some advices.
Thank you very much!

Re: Module for calculation SAD motion estimation using 2D-Tr

Hi,
I recently did a Motion Estimation Block Design, as a uni project, but i could'nt understand what you are exactly wanting.
If you want you may see the project deails at

Thank you for your help, your project is very good but maybe difference from my topic. My topic is implementation calculation SAD on FPGA. And now I do not know how to code module control that map reference pixel to 2D-Tree Architecture. By the way, thank you very much!
For example:
+ First 4 clock, load 4x4 reference pixel to module calculation.
+ Next clock, shift that pixels to 2D-Tree Architeture for calculation SAD.
+ Next clock, load remain reference pixel until whole search window is inputted.
The module control implement that function, I am not sure so I need further helps.

sir, Here iam attaching the base configuration block of motion core architecture of my project... Iam trying to write the vhdl codes for it...

But iam not getting the exact fuctionality of the architecture to write vhdl code..

So can you please help me..

kindly do the need...

Thanks in advance...
