What is µC/OS-III?
µC/OS-III (pronounced “Micro C O S Three) is a scalable, ROMable, preemptive real-time
kernel that manages an unlimited number of tasks. µC/OS-III is a third-generation kernel and
offers all of the services expected from a modern real-time kernel, such as resource
management, synchronization, inter-task communications, and more. However, µC/OS-III
offers many unique features not found in other real-time kernels, such as the ability to
complete performance measurements at run-time, to directly signal or send messages to tasks,
and more.
Why a new µC/OS version?
The µC/OS series, first introduced in 1992, has undergone a number of changes over the years
based on feedback from thousands of people using and deploying its evolving versions.
µC/OS-III is the sum of this feedback and experience. Rarely used µC/OS-II features were
eliminated and newer, more efficient features and services, were added. Probably the most
common request was to add round robin scheduling, which was not possible for µC/OS-II, but
is now a feature of µC/OS-III.
µC/OS-III also provides additional features that better exploit the capabilities of today’s newer
processors. Specifically, µC/OS-III was designed with 32-bit processors in mind, although it
certainly works well with 16- and even several 8-bit processors.
