It’s amazing to see this and the similarities to my Amiga VA2000 graphics card that I did many years later, but I swear I didn’t see this before. VA2000 did HDMI output and some very basic 2D acceleration. It’s now sold out.
I just completed the PCB design for ZZ9000 (firmware is in beta already), a bigger follow-up based on ZYNQ and using the ARM cores for some graphics and general purpose acceleration. It will be open sourced as well.
Do you think there is demand to spin an open HD framebuffer+ARM card for other platforms as well?

- vardump 7y agoHow much did the HDMI license cost? Been looking for HDMI output for a retro system, but it DVI would incur no cost, while HDMI would require extra $5k.
- MisterTea 7y agoYou can output DVI using an HDMI connector and not pay the license fee. So "DVI output via HDMI connector" gets you around the license fee. The fee comes in when you use the actual HDMI spec and implement HDMI stuff like Audio, CEC and actually calling it HDMI.
- vardump 7y agoDVI is indeed my approach to get around the issue. Like you mentioned, the downside is losing those nice extras, like audio.
- colejohnson66 7y agoSlightly off topic: why did HDMI become the de facto standard when DP and DVI have no licensing fees?
- opencl 7y agoSome combination of: HDMI consortium is backed by numerous large TV manufacturers and movie studios, DVI lacks audio support, HDMI already had a lot of traction by the time DP was released, DP initially lacked HDCP support, HDMI supports much longer cables than either DVI or DP.
