Logic Destroyer — Proven in Silicon. @logicdestroyer.bsky.social · 04/10/2026KianV StealthV — my custom quad-core RV32IMA RISC-V SoC on FPGA, running Linux SMP. Fixed-point bounce physics: gravity, impacts, squash and stretch. Four CPU-pinned threads render the floor, shadows and balls, including depth testing, directly to /dev/fb0. Precomputed lighting, no FPU. 3433
Logic Destroyer — Proven in Silicon. @logicdestroyer.bsky.social · 03/10/2026Bros, remember Bruno’s world-famous donut? That was always kind of a benchmark for me. Bare metal on my 5-stage core. Now look at this shit. My custom SystemVerilog SoC, KianV StealthV, running quad-core Linux. MMU, memory bandwidth, audio, video. A complete system. And I’m still not done. 160
Logic Destroyer — Proven in Silicon. @logicdestroyer.bsky.social · 30/09/2026Yo brothers. I’ve been working on my quad-core again. Still no L2 cache for the moment. MP3 decoding, Bunny mesh in the framebuffer, X server, xeyes, analog clock with seconds, loader, CoreMark above 2 per MHz per core × 4, htop across all four cores. KianV Stealth 010
Logic Destroyer — Proven in Silicon. @logicdestroyer.bsky.social · 30/09/2026Pretty fucking cool to see 1.5473 CPI on this thing. Four cores, Linux, MMU, DDR3, caches, video, audio, networking, SDIO. When this project started, it was a bare-metal pipelined CPU running directly from block RAM. No DDR, no caches. Around 1.1 CPI. 150

Logic Destroyer — Proven in Silicon. @logicdestroyer.bsky.social · 01/09/2026Looks like native GCC and G++ are now working on my dual-core. Fuck yeah. KianV. StealthV. 020
Logic Destroyer — Proven in Silicon. @logicdestroyer.bsky.social · 29/08/2026And the cool thing is, that’s with video, audio, networking, and all kinds of other stuff sharing the same memory bandwidth. That’s pretty damn cool. 000
Logic Destroyer — Proven in Silicon. @logicdestroyer.bsky.social · 29/08/2026Small update: I now have dual-core SMP with a CoreMark > 2, without an L2 cache. Pretty damn cool. KianV StealthV Gangster SoC 120
Logic Destroyer — Proven in Silicon. @logicdestroyer.bsky.social · 22/08/2026Quick KianV StealthV Linux SoC update: the dual core is now playing MP3s while rendering the MIT Bunny with Gouraud shading. Nice to see it all running together! 020
Logic Destroyer — Proven in Silicon. @logicdestroyer.bsky.social · 21/08/2026Still on vacation, bored, family’s not around… so I’m writing demos for my SoC because I don’t feel like doing logic design right now. 😄 StealthV This is a custom wizard. 030
