Could the source code of WP452 regarding VivadoHLS be provided ?

Hello,everyone. I am a newbie to Vivado HLS. Now I want to study digital beamforming on FPGA. I found this document---- Adaptive Beamforming for Radar: Floating-Point QRD+WBS in an FPGA (WP452) It is really attractive. However, there are no souce codes. I do NOT know how to implement QRD algorithm with Vivado HLS. By the way, I found the example project of qr_inverse alter Vivado HLS was installed. It seems that this example just call a library function of QRD which is meaningless to me. Could anybody share the source code of WP452 ??

Hi @jlqsczw_2007

 

I'm not aware that source code for white papers are usually made available or published.

I thought this was to be taken as someone "skilled in the art" should be able to investigate and reproduce similar design(s).

 

For lib calls, all the code is available in include files. Either use the GUI to navigate / go to source declaration (os that F2 or F3 in VHLS GUI/Eclipse??) or grep the include files/directory directly.

 

I hope this helps.

- Hervé

Can you do QRD in C++ or Matlab or any other language? That's all you need to start. Did you see this paper http://www.hpsp2015.com/talks/Daniele%20Bagni.pdf ? (Not sure if it's the same as wp452)
Here is extract from a book which has c code for qr decomposition: http://www.aip.de/groups/soe/local/numres/bookcpdf/c2-10.pdf

It used to be that Applications Note NNN (not a White Paper, I know) were available here:

 

http://www.xilinx.com/support/documentation/application_notes/xappNNN.pdf

 

and would have source code here:

 

http://www.xilinx.com/support/documentation/application_notes/xappNNN.zip

 

When the source code was not protected by another non-disclosure agreeement.

 

Can you find an application note that has what you need?

 

Daniel

@jdusari ,

Xilinx never shares files for white papers. The link that was present in the Design Hubs page was mistakenly published few months ago and when this was pointed it has been removed from the Design hubs of Xilinx site.
