Reliable Microkernel Architecture

The core of the μ-velOSity RTOS is an efficient and reliable kernel with minimal footprint and a clean API. It enables applications, middleware, and drivers to operate outside the kernel memory space.

The system comes with three pre-defined build configurations (speed-optimized, size-optimized, or debug-optimized), allowing developers to quickly adjust RTOS behavior or create custom configurations to meet specific project requirements.
