1.3. Boot Duration
In some applications, the duration of the boot process is very critical, and it needs to meet a certain constraint.
This section presents some considerations on optimizing the boot time, together with some measurements taken with various options on the Cyclone V Development Kit.
The elements that compose the boot time for a typical Linux system are depicted in the figure below:

A typical bare-metal application boot time is depicted in the following figure:

Note: The above figures are not drawn to scale - each stage is depicted with the same size.
