Hello dear Gurus and normal guys.
I have a question : When i connect camera 8 bit to the
Artix 7 (XC7A100T 18kb bram -270 36kb bram-135 max kb-4,860)
i can use BRAM for camera 640x480x8 8bit,when framevalid and linevalid on, counter starts to work and make address,wr enabled then on camera pixelclk saves camera data to bram.. and when vga worked when vertical sync and horizontal synch is on it reads data on 25 or 75 mhz.
but when i use 1280x720x8 8bit BRAM is not enough..
so I have on ztex board ddr3 256mbyte, there are 128 bit bus.
camera output is 10 bit, 8 bin enough, how to connect to DD3 ? how to store 1280x720x8 bit ? but bus is 128 bit not 8 ? and how to confugre like in case of BRAM ?
