µC/OS-III™ Real-Time Operating System
Micrium µC/OS-III™ Real-Time Operating System are designed to save time on embedded system projects. In addition to the features inherent in μC/OS-II, μC/OS-III also manages a nearly unlimited number of application tasks, and features an interrupt disable time of near zero. Micrium µC/OS-III™ Real-Time Operating System support ARM7/9, Cortex-MX, Nios-II, PowerPC, Coldfire, i.MX, Microblaze, RX600, H8, SH, M16C, M32C, Blackfin, and more. Ports are available for download from the Micrium website.
μC/OS-III manages seemingly unlimited application tasks, constrained only by a processor's access to memory. μC/OS-III also supports a nearly unlimited number of priority levels. Typically, configuring μC/OS-III for between 32 and 256 different priority levels is adequate for most embedded applications. μC/OS-III allows for nearly unlimited tasks, semaphores, mutexes, event flags, message queues, timers, and memory partitions. The user allocates all kernel objects at run time. μC/OS-III provides features to allow stack growth of tasks to be monitored. While task size is not limited, they need to have a minimum size based on the CPU used.

The user allocates all kernel objects at run time. μC/OS-III provides features to allow stack growth of tasks to be monitored. While task size is not limited, they need to have a minimum size based on the CPU used. The footprint of this OS can be scaled to only contain the features required for a specific application.
μC/OS-III allows multiple tasks to run at the same priority level. When equal priority tasks are ready to run, μC/OS-III runs each for a user-specified time. Each task can define its own time quanta and give up its time slice if it does not require the full time quanta. μC/OS-III's footprint can be scaled to only contain the features required for a specific application. The execution time for most services provided by μC/OS-III is both constant and deterministic; execution times do not depend on the number of tasks running in the application.
μC/OS-III has a number of internal data structures and variables that it needs to access atomically. It protects these critical regions by disabling interrupts for almost zero clock cycles, ensuring that it is able to respond to some of the fastest interrupt sources. Interrupt response with μC/OS-III is deterministic.
