DESCRIPTION:What would have resembled a console hardware dedicated to our b
 eloved retro-games from the early 90's\, such as Doom 1993 and Comanche 19
 92? I invite you on a journey to answer this question\, not using emulatio
 n\, not using a micro-controller\, but designing our own hardware running 
 on an entry-range ice40 UP5K FPGA\, using a fully Open Source toolchain. \
 n\nWe'll dive into the rendering technology of the era\, which was not pol
 ygon based in the traditional sense but rather based on clever tricks akin
  to ray-casting. We'll see what parts are critical to accelerate and how t
 o achieve that in a limited gate-count (< 5K LUTs)\, while still reaching 
 320x240 pixels realtime rendering with full resolution textures.\n\nThe re
 sult fits entirely into the FPGA and its accompanying SPI-flash chip\, and
  uses a low-cost SPI-screen. This turns your dev boards into a fantasy ret
 ro-console.\n\nSo buckle up Marty\, we're going back to the future to re-i
 nvent the GPU!
