Goals: develop free, portable, small, well-designed RTOS for embedded hardware platforms: SBC (Single Board Computers), SOM (System on Module), SoC (System on Chip). Free.

Portable, small, realtime microkernel 32-bit OS for embedded systems, coded in C, POSIX emulation layer. Open source, BSD.

Realtime microkernel: preemptive, fully re-entrant, multithreaded, SMP, continuations, full locking primitives; shares many ideas with Mach, developed by CMU in late 1980's, early 1990's, stopped in 1994. [Open Source, GPL]
