Hello,
  I have a similarly OT question as Nicolas.

  While working on my Ethernet attached TFT, I need to decide where to
"cut" the video output chain. The choices are:

  *) X driver: the interface might have acceleration, but I'm not sure
if modern apps (kde/gnome) use the line drawing, or they just do bitmap
copy on almost everything. I hope that at least scrolling can be
accelerated this way.

  *) Use an invisible framebuffer and implement own change transmission
protocol similar to VNC, optimized for 100Mbps.


  Other, which are be impossible (with a Spartan3E-500 & ATmega128):

  *) Use a standard VNC protocol

  *) Use X protocol


  Any other ideas?

  I would like to have an efficient system (not too much load on the
server & low latency) for desktop use (office apps, web browsing, code
writing).

  Capabilities of the device are: 100Mbps ethernet, 16MB sdram as
[EMAIL PROTECTED] (533MB/s peak), 18bit output up to 1280x800. There is a
Spartan 3E-500 and currently an 8bit risc mcu (ATmega128, 128kB eeprom,
4kb ram) for ARP/DHCP.

  The question of video (idct,yuv,scaling) will be solved separately, I
want to keep the device simple, with this cheap FPGA.

  Daniel
