Hello,
I'm working on a video-processing project. I've been able to program the FPGA and write to the SPI Flash for automatic booting.
Now, I'm trying to exercise myself on accessing the DDR2 128 Mbit RAM on Atlys board (Spartan6-based); which is one of the key-component for the final application (I want to use it as a framebuffer for retrieving the HDMI source).
But, to begin with... my idea is to create a simple example that works like this:
-every time user changes a switch, buttons status are written at a certain address in the RAM; The same values, then, are just read from the RAM and sent to the LEDs...
What I miss is the "know-how" to operate the RAM...
Can you guys suggest me some tutorial/guides/hints?
Thank you
