You must read the image:

I=imread('your_image-bmp');

Resize the image in order to access it from a plain rom

Ir=reshape(I',prod(size(I)),1);

Now you can generate your mif file:

miffile('your_image.mif',Ir,8,length(Ir))

Each pixel is coded using 8 bits. (gray scale images). If you are going to process true color images, you should instance 3 memories for each color plane.

This .mif file can be used in an altsyncram megafunction instantiated in ROM mode.

The index_rom is the address of the altsyncram. This logic must be implemented in your hardware.
