VGA controller

Started by damir December 7, 2005
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

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.

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.

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.
