SylixOS Profile

SylixOS is a large-scale embedded real-time operating system, was born in 2006, first it was just a small multi-task scheduler, after years of development, SylixOS has become a perfect function, high performance, reliable and stable embedded systems software development platform .

And SylixOS similar real-time operating system, the world's more well-known VxWorks (mainly used in aerospace, military and industrial automation), RTEMS (originated in the US Department of Defense Missiles and Rockets real-time control system) and so on.

SylixOS as a real-time operating system, a latecomer on the design ideas borrowed design ideas of many real-time operating system, making SylixOS reached or exceeded the level of many real-time operating system functionality and specific performance, as real-time domestic operating system best on behalf of one.

 

Functions and features of SylixOS

SylixOS as preemptive multitasking hard real-time operating system, has the following functions and features:
