However, uC/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, achieve pending on multiple kernel objects, and more. WHY A NEW uC/OS VERSION? The uC/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. uC/OS-III is the sum of this feedback and experience. Rarely used uC/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 uC/OS-II, but is now a feature of uC/OS-III. uC/OS-III also provides additional features that better exploit the capabilities of today’s newer processors. Specifically, uC/OS-III was designed with 32-bit processors in mind, although it certainly works well with 16- and even several 8-bit processors. uC/OS-III GOALS The main goal of uC/OS-III is to provide a best-in-class real-time kernel that literally shaves months of development time from an embedded-product schedule. Using a commercial real-time kernel such as uC/OS-III provides a solid foundation and framework to the design engineer dealing with the growing complexity of embedded design
