'''DSPnano''' is an embedded [[real-time operating system]] (RTOS) which is 100% compatible with [[POSIX]] and offers a 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 controller]]s and [[digital signal processor]]s [http://rowebots.com/Embedded_System_Software/DSP_RTOS].  Its parent was the [[Unison Operating System]].

Today DSPnano offerclaims 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 [[Field-programmable gate array|FPGA]] platforms to accelerate [[Digital signal processing|DSP]] applications.

Typical processors that DSPnano runs on today include: [[Microchip Technology|Microchip]] [[PIC microcontroller]] (24, 30, 33 and 32), [[Renesas Technology|Renesas]] [[M16C]], [[ARM architecture|ARM]] and more.[http://rowebots.com/products/dspnano]
