Multithreading

One of the advantages of using microcontrollers designed to build embedded systems is the possibility to run logically separated tasks within separate execution units by time-sharing the resources.

The most popular type of design for embedded software is based on a single loop-based sequential execution model, where modules and components are connected to each other exposing callback interfaces. However, modern microcontrollers offer features and core logic characteristics that can be used by system developers to build a multi-tasking environment to run logically separated applications.

These features are particularly handy in the approach to more complex real-time systems, and interesting to understand the possibilities of the implementation of safety models based on process isolation and memory segmentation.
