How much DooM can fit in a USB port? Quite a bit it turns out! A minuscule #Fomu #fpga board hosts my hardware/software re-implementation of the DooM render loop in the confines of a USB port (uses ~4200 LUTs and < 128 kB of internal RAM). (1/n)
This is a tiny piece of DooM in a 2.1x2.7 mm #fpga. That is pretty small! (can you see it below on the #Fomu board? you might have to zoom ...).
I created within a #riscv computer with specialized texturing and column drawing hardware. Designed to render DooM 1994 levels! (2/n)

The OLED screen is connected to the #Fomu through jumper wires soldered on the pads (a trick inspired by @brunolevy01 Fomu vga mod). (3/n)
