A picture is worth a 1000 words.
what am I looking for ?? SDRAM, VRAM, SRAM, RAMmyhead, should I be looking for ?? My implementation is what is called a ''data buffer'', all data is write and read sequentially.
Just for clarification, when I say write, RAM memory sends current frame to MCU, when I say read, DVI receiver is sending frame to RAM.
Important****I just need one that allows me to write from the chip with a lower frequency writing clock wich will be given by the MCU
I believe FIFO are not deep enough since my write out speed will be almost 20 times less at times. lets say a frame of dvi is 3.93 Mb, (1280*1024*3 bytes), so 3 930 000/24 = 163.75 Kb, each stream of parallel data needs to be near 160Kb deep.
I am just using this as a data rate matcher, my MCU cannot handle the speed of even the lowest resolutions of DVI since many real time calculations are done with the color.
Overflow and lost frames are of no importance, It would be great to start writing out the frame more slowly as it is still being read, but I have no problem just writing out a completed frame, processing with MCU then, clear memory and start read and latch to next new frame.
I hope everybody understand what I am trying to accomplish ??
Best regards,
