uC/OS-III

µC/OS-III is a highly portable, ROMable, scalable, preemptive, real-time, deterministic, multitasking kernel for microprocessors, microcontrollers and DSPs.

Features

  • Preemptive multitasking real-time kernel with optional round robin scheduling
  • Delivered with complete, clean, consistent source code with in-depth documentation.
  • Highly scalable: Unlimited number of tasks, priorities and kernel objects
  • Resource-efficient: 6K to 24K bytes code space, 1K+ bytes data space)
  • Very low interrupt disable time
  • Extensive performance measurement metrics (configurable)
  • Certifiable for safety-critical applications
