理论上来说只要是cpu都可以运行linux或unix，只要ram和falsh够大，原理是在单片机(无论是8bit，16bit，32bit，即使不带mmu)上模拟可以运行linux的cpu。

The relatively popular Digital Equipment Corporation (DEC) PDP-11 16-bit minicomputers started selling in the 70s, and were still available in the earlier 90s. While being stuck in Europe due to COVID-19 restrictions, Jeroen Domburg (aka Sprite_tm) decided to design a tiny replica of a DEC VT102 PDP-11 terminal based on ESP32 wireless SoC and running 2.11 BSD UNIX through SimH PDP11 emulator.
