VGA controller |
|
|
I'm looking for simple VGA (XGA up to 800x600) controller for displaying
simple images on the LCD pannel - any suggestion for available ASIC (LCD
controller) or FPGA (VHDL core) design will do. Thanks,
Damir |

I've found reference design from Xess for their Xilinx boards - it's for
standard VGA, but as you've said - translation for digital flat pannel
interface shouldn't be a problem.

there are plenty of them, do your homework.
opencores has something, xilinx reference designs include them, and there
are other VGA controllers ipcores as well.
and most likely non of them suites your needs as it is really dependant on
your SoC bus and memory being used.
the VGA is simple (LCD even simpler) if... you have high speed easy to use
large fast memory for frame buffer. if not then it not so simple any more.
look at ML401 reference design there is VGA core on PLB bus, its for non
LCD but modification to LCD would be really simple.

Currently I'm looking only in 800x480 resolution with (if possible) 18-bit
color (16 bit is also ok) and flat-panel digital RGB interface.
