Winix is a minimal, hobbyistic, educational and UNIX-style Operating System for the Waikato RISC Architecture Microprocessor (WRAMP).
Inspired by the Minix1 operating system, Winix includes a full-featured kernel with features such as process and memory management, in-memory file system, exception control, and a user space bourne shell with interactive command line. And, for a bit of fun, you can even play the classic game of snake by simply typing snake
in the command line.
- Kernel Memory Management: virtual memory, page mapping
- Process Management: Kernel thread, process creation
- Exception control and interrupt handler
- In-memory file system that supports most of the POSIX api
- A Bourne shell supporting multiple pipes and redirection
- User memory management: malloc() free()
- User coroutine with
ucontext.h
support - Stacktrace dump, segfault analysis
