Rickroll Meme Immortalized In Custom ASIC That Includes 164 Hardcoded Programs
Friday April 5, 2024. 02:45 AM , from Slashdot
Bitluni was a late inclusion on the Tiny Tapeout 2 project, having been invited just three days before the submission deadline. He initially just made a persistence-of-vision controller, which was revised twice for a total of three designs. 'At the end, I still had a few hours left, and I thought maybe I should also upload a meme project,' Bitluni says in his video documenting his ASIC journey. His meme of choice was of course the Rickroll. One might even call it an Easter egg. However, given that there were 250 total plots for each design, there wasn't a ton of room for both the graphics processor and the file it was supposed to render, a short GIF of the music video. Ultimately, this had to be shrunk from 217 kilobytes to less than half a kilobyte, making its output look similar to games on the Atari 2600 from 1977. Accessing the Rickroll rendering processor and other designs isn't simple. Bitluni created a custom circuit board to mount the Tiny Tapeout 2 chip, creating a device that could then be plugged into a motherboard capable of selecting specific designs on the ASIC. Unfortunately for Bitluni, his first PCB had a design error on it that he had to correct, but the revised version worked and was able to display the Rickroll GIF in hardware via a VGA port.
