       @rl_dane @mdc I wonder how #uxn opcodes compare to what F18 chips from #GreenArrays have. Only 32 opcodes, 8 of them special (can be used in th last 3 bits of a kind of 18-bit #VLIW word) versus 256 opcodes of #uxn#varvara offers much more high level i/o, F18A has 4 interchip ports, GPIO, A/D interface and SERDES, which can be used to build things like Ethernet for example.varvara-fpga does not implement most varvara I/O features at all.https://www.greenarraychips.com/home/documents/greg/DB001-221113-F18A.pdfhttps://www.greenarraychips.com/home/documents/greg/PB004-110412-F18A-IO.pdf

       @saper @rl_dane @mdc which I/O features are missing?https://codeberg.org/tsalvo/openfpga-varvara
