A fast (190 cycle context switch), small (1-1.5 K), designed and optimized for next generation DSP systems; and Fusion Net (TCP/IP Stack), Fusion Web (services); all support priority based, realtime, preemptive, multitasking. By DSPOS, Inc.
Modern message-based architecture. Introduced June 1992, many uses: cell phones, small handheld devices, large factory automation systems, Space Shuttle.
Realtime preemptive kernel coded fully in C, so is highly portable to different hardware platforms and easily embeddable; Descriptions, full source code, examples, C Style Guide and programming Guidelines. [Free]
A RTOS for high safety systems, brick-wall time, space partitioning of separate loaded programs with different levels of criticality, for greatly reduced test, certification costs, compliant to ARINC653 open system interface definition. By BAE Systems...
Makes, sells, supports embOS RTOS for embedded uses, multitasking, minimum cost, no royalty, fully interruptible, efficient for time critical uses, RAM and ROM needs so small it fits 1-chip uses, leaving more room for user programs.
