January 2010 marks the first public release of the Atomthreads open source RTOS. Intended for embedded systems developers who require a simple lightweight scheduler to incorporate in their projects, it provides real time threading support and standard RTOS features within a few small, highly portable files. Released under the flexible BSD license, Atomthreads provides a free solution suitable for commercial use without royalties or restrictions.

Embedded systems developers considering other open source operating systems but who do not need or already have their own IP stack, file systems and other components can benefit from the reduced complexity and effort of integrating only a simple scheduler library. Similarly
developers who might otherwise roll their own in-house scheduler can save both development and validation time by dropping in this ready-made and fully validated scheduler library. Atomthreads offers such projects a solution which reduces development time and costs.

Atomthreads has been developed with portability in mind, and can run on any CPU architecture. An initial port is available for the Atmel AVR/ATmega architecture, with additional ports in development including 8-bit, 16-bit and 32-bit architectures.
