The Almost Real-Time Target is a target definition to Real-Time
Workshop from Mathworks. It is called almost real-time, because it
simply sleeps the running process a complete step size. The actual
step size of the model execution is therefore the step size plus the
execution time, hence the name Almost Real-Time.
It is a quick way to test the code, and interface it in real-time from
Simulink in external mode, and it is compatible with multiple
platforms, and easy to use.
