Honored ContributorError (10500) for storing coordinates pixel of a binary image
Hi. I am novice working with FPGAS, I want to add all the coordinates pixels of an image, and each pixel is composed by a coordinate pair (i,j) But I have a mistake when I compile my code.
I previously saved the mif file into ROM. My binary image is 256x256 I really need the help.:cry: Thanks!
