#2This is a cool project! Is there any info available on the utilization numbers for the core? I'm curious how it stacks up against Xilinx's HDMI bloatware.

#3Pixel clocks... haven’t thought about those in a looooong time. When my old 14” packard bell monitor world act up i would bust open x11config and taze it with a hilariously overdriven clock.
Probably should be illegal.

#4Nice! Everything I'd seen before was DVI.
What about HDMI input? What I'm imagining is an HDMI freeze button, to buffer a single frame. Many projectors have that feature built in, but some don't, and I wish I could build it as an external hardware device.

Here's the usage on my Cyclone 10:
Info (21057): Implemented 1509 device resources after synthesis - the final resource count might be different
Info (21058): Implemented 15 input pins
Info (21059): Implemented 33 output pins
Info (21060): Implemented 87 bidirectional pins
Info (21061): Implemented 1240 logic cells
Info (21064): Implemented 128 RAM segments
Info (21065): Implemented 2 PLLs

Huh. Why is that useful? (Since some projectors have it built in I imagine there's a use case I'm missing.) Splash screen while you figure out your presentation on your mirror but without the stress of your audience watching you click around?

I would live HDMI input also, but for different reasons. I want to process video from HDMI streams.

#8Your systemverilog is quite readable and well written. Good work on the library. Always a pleasure to see people using stuff I developed (used to work on Quartus)

Thanks! I was originally writing in Verilog but made the switch after coming across multidimensional packed arrays, which made the audio implementation easier.

Mike Field has something in VHDL for this: https://github.com/hamsternz/Artix-7-HDMI-processing
