Honored ContributorHi all, please I need your help with this issue,
I save my image as text ( 256 * 256) gray scale, and I want to load it to SRAM before start modifying it, but I have no glue how , I meant to use VHDL with NIOS to be able to manage my image using pure VHDL. Thank you.
Honored ContributorThere is an option to initialize memory blocks with custom data. It should be fine if you need to modify your initial image seldom.You can create such memory initialization file with Quartus and when creating memory block guide the wizard to it.
Honored ContributorHonored ContributorIt works fine here. I use MegaWizard Plug-In Manager. When creating ROM IP I just select my mif file unter Parameter Settings / Mem Init / Browse and it does the rest.
Honored ContributorHonored ContributorWell, in this case you also need SRAM controller connected to the same bus as ROM is and then some bus master to copy all the data from ROM to SRAM. Either you write your own module to do that or use Nios.
Honored ContributorHonored Contributor??? The memory megafunction ROM/RAM has already the contents of mif file after synthesis inside. At least it should. Or it isn't your case? Then you need open a ticket at Altera's support.
Honored ContributorThere are further steps I am already searching for them. thanks
