Creating ip for image processing

[aparna_g_r]

Hello, 

I am working on a matrix 256*256 and want to find the absolute of matrix.  Can anybody please help me about this?? 

Thank you in advance

Hello @aparna_g_r,

Images are processed as stream of pixels in FPGA. So you can think of processing it on each pixel. I assume that you want to find the "Absolute Value" of the given image. If the data is "floating point" then "Floating Point IP for Absolute Value" can be used. Or if the data is in "fixed point" format then simple 2's complement arithmetic technique can be used.

Hello urvish@htic

Thank you for reply. Can you please suggest me the sample code as I am new to HLS.

Dear @aparna_g_r,

Please tell me whether you are working with fixed/floating point arithmetic. I can give you a VHDL based implementation.

Hello urvish@htic

I am working on a complex data and I need to take ifft of it the find the sum of square values.  I am looking forward to create an IP using hls and use it in vivado. 

Thank you,

Dear @aparna_g_r,

I do not have an extensive experience with Vivado HLS. I prefer writing the codes using HDL. So I might not be able to help you more in this regard.
