Baochip-1x: A Mostly-Open, 22nm SoC for High Assurance Applications
hardware-research

Baochip-1x is a mostly-open, custom 22nm RISC-V SoC featuring a 350MHz Vexriscv CPU with MMU, cryptographic accelerators, and secure element features, designed for high-assurance applications running the pure-Rust Xous operating system. The chip breaks embedded SoC convention by including memory management unit protection (typically only found in high-end processors) to enable secure, isolated application execution and address space relocation without proprietary workarounds.
