How can I design a simple graphic card ?

 

[treqer]

simple - easy)))) primitive - very easy))))
what specifically are interested in?

with some PCB tools.

with a pic : **broken link removed**
video signal generation : **broken link removed**
with a cpld : ELM - General purpose display controller

hope this helps !

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 .

can you please present projects that have displayed a photo from mmc ?

how about you do some of your own work?

 

[mrflibble]

Didn't you get the memo? All the hip kids in town post terse descriptions of their problem and expect you to do the work.

Sorry, I meant to say their URGENT!!!!11!!!ONEONE!!! problem. halp plz!

it is not easy))))
it requires a controller SD_MMC /
block in the file system (processor)
display unit of memory -> VGA
arbitter memory

yes i know
can you describe more , Please ?

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 ?
