Read from sd card an image on DE2-115

Pretty good task for a pure verilog implementation. I'm assuming this means you can't instantiate a NIOS cpu core and write some C code.

First things first, is how can you simply the problem. What Image format must it be in. If you can choose one, choose the simplest, (BMP or PPM), then if you don't have to have a FAT system, don't, just write the data raw to the SD card at a specific offset so you can READ it raw from the SD.

Then store it in a faster memory, (internal if you can), so that you can loop the output and not have video underrun's when displaying the image.

Once you have the simplest form running, you can start looking into more advanced features, like dealing with FAT tables, and different image formats, etc.
