VGA/LCD Controller

I am  using TFP410 DVI chip, I want to interface with this fpga, any one have VHDL code

DVI interface

Could  send me scheme of progect and example

Scheme

A 12 bit dvi interface. Front page says its included yet i cant find it in the documentation.

12 Bit DVI

Regardless of the fact that this function was not used in design it has the wrong comment and implementation (vga_fifo_dc.v:129)
gray2bin is not simple bin2gray on bin
here is right function
function [AWIDTH:1] gray2bin;
		input [AWIDTH:1] gray;
                integer i;
	begin
                for (i=1;i<AWIDTH;i++)
		  gray2bin[i] = ^(gray>>(i-1));
	end
endfunction

wrong gray2bin conversion

I think TV-OUT capability would be a nice addtion. I don't mean RF TV, but a video signal such as that in RCA jacks we plug to the TVs.

TV-OUT?

It would be a nice to have the ability to use this core to control an STN lcd module.  Modes should include 1 bit per pixel (1bpp), 2bpp, 4bpp.  Single/Dual scan (upper half/lower half).  4/8 bit data bus.  Up to 1024x768.

I have designed this type of controller many times in many ASICs, and would like to help, but I do not know if my employer would allow me to.  I will look into this.
