VHDL and Video

[Amit]

hello group,

I'm trying to understand how VGA works using VHDL in terms of vsync
and hsync signals. Does anybody know any good online tutorial? also I
need to learn how to create RGB output.

Your help is appreciated.

Regards,
Amit

VGA section:

In essence: Clock pixels -> Divide by Hsync -> Divide by Vsync, done.
Oh and ofcourse feed those pixels to the RGB.
