OpenBSD vs MQX RTOS: What are the differences?

OpenBSD: Free and open-source Unix-like operating system. It is a free and secure UNIX-like operating system that emphasizes portability, standardization, correctness, proactive security & integrated cryptography; MQX RTOS: Real-time operating system that provides real-time performance within a small, configurable footprint. It is designed to have a modern, component-based microkernel architecture allowing for customization by feature, size, and speed by selecting the components engineers wish to include while meeting the tight memory constraints of embedded systems.

OpenBSD and MQX RTOS can be primarily classified as "Operating Systems" tools.

Some of the features offered by OpenBSD are:

• API and build changes
• Kernel randomization
• Memory protection

On the other hand, MQX RTOS provides the following key features:

• Small Code Density
• Component-based Architecture
• Full and Lightweight Components
