RetroBSD 是Unix 2.11BSD 的一個移植版本，主要用于固定內存映射的嵌入式系統。當前目標是 Microchip PIC32 微控制器，包含 128K 內存和 512K 閃存。PIC32 處理器使用 MIPS M4K 架構，可執行數據內存和在用戶和核心模式下的靈活的 RAM 分區。
嵌入式 BSD 系統：RetroBSD

主要特性

  • Small resource requirements. RetroBSD needs only 128 kbytes of RAM to be up and running user applications.
  • Memory protection. Kernel memory is fully protected from user application using hardware mechanisms.
  • Open functionality. Usually, user application is fixed in Flash memory - but in case of RetroBSD, any number of applications could be placed into SD card, and run as required.
  • Real multitasking. Standard POSIX API is implemented (fork, exec, wait4 etc).
  • Development system on-board. It is possible to have C compiler in the system, and to recompile the user application (or the whole operating system) when needed.
