just Simple

with some PCB tools.
If you give me a schematic file , I will .
I need to know how can I design its circuits .

a ttl example : Masochist's Video Card - Introduction | PyroElectro - News, Projects & Tutorials
with a pic : **broken link removed**
video signal generation : **broken link removed**
with a cpld : ELM - General purpose display controller
hope this helps !

about the video. Requires intermediate video memory. The size should match the resolution and color depth. For 1024 * 768 and 16 bit color (5-5-6) 1024 * 768 * 2 bytes. Static memory, you can connect yourself. For the dynamic - it is better to take a ready-made controller.
For this controller, if it requires one port will produce an arbitrator.

---------- Post added at 12:27 ---------- Previous post was at 12:22 ----------

The arbitrator will distribute access continuous reading from the memory of VGA DAC and record the new values ​​of the processor.
Controller sd_mmc - access device to the card. In the simplest case, this SPI controller.
The processor must read the file from the card and turn it into a sequence of bytes to write to video memory.

Tanks a lot it was so helpful . but I have questions :
1024*768 and 32 bit color it should be 1024*768*4 Byte : 3145728 Byte : 3072 KB : 3MB
Do you mean something like SRAM ( as a static memory) ?
Can ARM Cortex-A series be used as a processor in VGA Card ?
