DSPnano is an embedded real-time operating system (RTOS) which is 100% compatible with POSIX and offers a tiny tiny embedded Linux compatible solution. It was first created in 1996 and was one of the first pthread based real-time kernels. Its entire focus was on tiny real-time digital signal processing systems and has been optimized to deliver high performance DSP on embedded digital signal controllers and digital signal processors . Its parent was the Unison Operating System.
Today DSPnano has been moved to an open source model and offers full POSIX capabilities for threads, communication, synchronization and I/O. A full complement of I/O is included as is a full complement of DSP optimized features including: DSP libraries, fix size buffer management, software pipelines and more. It has also been moved to FPGA platforms to accelerate DSP applications.
