NuttX is a real-time operating system (RTOS) with an emphasis on standards compliance and small footprint. Scalable from 8-bit to 32-bit microcontroller environments, the primary governing standards in NuttX are Posix and ANSI standards. Additional standard APIs from Unix and other common RTOS’s ... [More] (such as VxWorks) are adopted for functionality not available under these standards, or for functionality that is not appropriate for deeply-embedded environments (such as fork()). [Less]

Upthreads is a user space implementation of the POSIX thread library implemented using setjmp/longjump (or equivalent). This libpthreads implementation is useful when threads are need in deeply embedded systems with little OS support.
