DNA-OS is a French-made operating system to supersede MutekA, an obsolete operating system, while still providing POSIX thread API. As said on the SoCLib website, "It is a kernel-mode lightweight operating system for Multiprocessor System on a Chip. It is built on top of a thin HAL to ease porting on new platforms and processor architecture. DNA/OS does not support virtual memory."
DNA-OS is a layered microkernel operating system, written in C99, released under the GNU GPLv3 license.
