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.
