Redneckerz Posted January 19, 2021 Introduction: Remember the Doom on a FPGA thread? Ofcourse you didn't, you didn't comment on it! ;) In it, Sylvain Lefebvre describes his DOOM-Chip - Essentially a custom chip (No processor!) made on a FPGA to solely play DOOM. The Doom algorithm/rendering is 666 (heh) lines of code. A complete description is given, so stop by at the following link: But Lefebvre has gone much, much further. Introducing the DOOM_Demon. So what is the DOOM_Demon? The DOOM_Demon is a RISC-V based processor that acts as a co-processor to the DOOM-Chip. All game logic is moved over to this specialized processor. This ofcourse allows for completely new effects. In the video below, a platform is raised showing an interactive texture doing the melting effect from within Doom, calculated by the RISC-V processor. It also highlights that the DOOM_Demon is aware of its surroundings, showing off some impressive dynamic lighting effects. Additional details: Lefebvre has written an extensive explanation on how the DOOM_Demon works. Because all data is visible to the co-processor, it can manipulate everything in the scene. I have put this under a spoiler to keep the thread readable. This, along with @kgsws ACE Engine is a monumental and unique expression on the question: ''How can we play Doom?'' and its beyond fascinating.@Doomkid get in here! :P Spoiler 7 Share this post Link to post

Azuris Posted January 19, 2021 Ok, thats something really surprising and impressive. I've once read that it is only one Step between beeing a Genius or a Maniac. And i love everything and everybody jumping forth and back on this small Line (also doing it myself). This definivly does it. 0 Share this post Link to post
Dark Pulse Posted January 21, 2021 Coming soon, Doom is modded into a game of Monopoly. Do not pass Go. Do not collect $200. Do not retain your soul. 1 Share this post Link to post

I am aware that these unusual threads don't generate as much recognition as asking why a Zombieman is green or how Lost Souls travel through the air, but unusual Doom is still Doom, however unusual. It does not beat Doom on a pregnancy test, but its surely a completely nerdy and visually impressive way to do Doom. 1 Share this post Link to post
