mips_os

A very light shell with simple filesystem and memory manager. Developed for a student project on a MIPS processor and MIPS emulator (QEMU)

COMPILE & RUN

Require QEMU and mips-gcc-* tools

See settings.h to specify intall directory: export PATH="$PATH:/opt/mips-tools-cep/bin"

To execute on your computer with the real libc:

make pc && make run_pc Will generate os_pc.

To compile for qemu (with mips-libc):

make mips Will generate os_mips.

To execute with qemu: make run_mips
