Toasters vs phones, fight!
Baochip-1x: What It Is, Why I'm Doing It Now and How It Came About
Tiny chip promises phone-style safety; fans hype, purists demand proof
TLDR: Baochip-1x adds a memory manager so a tiny chip can run safer, phone-like apps. Comments cheer the security push, but argue over transparency, closed bits, core counts, and whether you can literally hand-type code—turning a niche hardware drop into a viral trust debate.
A tiny chip just sparked a big internet argument. Baochip-1x, from hardware hacker bunnie, packs a “grown‑up” memory manager—think phone-level app isolation—into a microchip that usually acts more like a toaster. Bunnie says the tried‑and‑true MMU (memory protection from the 1960s) is old but gold, like AES, and beats fancy new stuff for practical security. Cue comments lighting up with equal parts applause and interrogation.
Supporters gush about “trusted computing,” while skeptics demand receipts. gzread wants to verify the silicon (“is it really what it says?”), and intrasight pokes the hornet’s nest about “partially open” design—why aren’t all parts open? Meanwhile, K0balt shows up with hype math: “so there’s 5x RISC‑V cores?” And alexisread goes full retro, asking if they can literally hand‑type a tiny kernel into the chip’s memory. The vibe: half security pep rally, half courtroom cross‑examination.
Bunnie briefly pops in—“Hello wonderful people!”—then vanishes due to timezones, leaving the thread to marinate in memes. Top joke: “My toaster’s about to run Linux.” Top drama: “Open‑ish vs fully open” and “trust but verify.” Bottom line: if microcontrollers usually skip MMUs, Baochip-1x crashing this party is the plot twist people didn’t see coming.
Key Points
- •Baochip-1x’s defining feature is an MMU, enabling virtual memory isolation and secure, loadable applications.
- •The MMU’s page-based protection, dating to the 1960s, remains a proven cornerstone of modern operating systems.
- •Newer mechanisms (CHERI, RISC-V PMP, MPUs) are acknowledged, but the MMU is chosen for practicality and can coexist with them.
- •Without an MMU, small CPUs cannot run OSes like Linux, BSD, or Mach, and lack transparent address space relocation and swap.
- •Historical and market factors—especially ARM’s 1990s designs and A/R/M series segmentation—led microcontrollers to omit MMUs, using MPUs instead.
