I can't seem to wrap my head around the math.
Assuming I want a
640x480x256 VGA signal, and I had an FPGA or fast micro-controller to drive it, would
55ns be able to handle it?
Meaning each byte of the 8-bit memory would translate to one pixel. Also assuming my R-2R ladder was setup to something like
I have a very specific reason to use DIP SRAM. I can find speeds down to about
15ns but small sizes. The
512k I want to buy tops out at
If someone could give me examples of how the bandwidth is calculated, it might help me decide to use the 512k or maybe do something different with multiple 15ns chips.
