Fusion Embedded™ License-Free RTOS

Free Commercial Real-Time Operating System

The Fusion Embedded RTOS (Real-Time Operating System) from Unicoi Systems is a Real-Time OS designed and optimized for networking and media-centric processors. It is priority based, preemptable, deterministic and protects against priority inversion. Best of all, the Fusion Embedded RTOS is now license-free!

The Fusion Embedded RTOS is currently available for the following processors: Motorola DSP 56800E, Blackfin® processors from Analog Devices, and Freescale™ PowerPC. For questions about support for other processors, please contact

Fusion Embedded RTOS started in 1998 as DSP OS. It targeted media applications for DSPs. Since then it has evolved into a more general RTOS System, yet it has maintained all of the strengths that made it successful for DSP applications. These strengths include small footprint, objects for streaming data, very low processor overhead, stack sharing capabilities and fully integrated interrupt controls.

Fusion Embedded RTOS is deterministic and independent of the number of objects or tasks. Included is a Name server to name and use Fusion Embedded RTOS components as well as user created components. Additionally, you will have access to the Fusion C Library -- a small footprint, re-entrant, thread safe, integer based C Library. The Fusion Driver Model I/O Manager and Fusion Shell command line debug tool are included as well.

The Fusion Real-Time OS provides an extensive set of RTOS Services, including task control, task communications, task synchronization, packet management, memory management, interrupt control and time management. Fusion Embedded RTOS is designed to allow you to quickly bring your products to market. It is easy to learn and use. It has been ported to a number of CISC, RISC and DSPs.
