	Using the previously presented software library stack is not the only possibility. The platform also includes SDL (Simple DirectMedia Layer) which is a library that was originally developed by Loki Entertainment, a company that specialized in creating Linux-versions of popular commercial games. It contains most of the code necessary to write games and implement low-level graphics. SDL is not covered by this material, but you can find the API (and other) documentation at [http://www.libsdl.org/ libsdl.org] .

	Low power consumption is one of main hardware design goals with mobile devices because of the limited electric charge in their power supplies. If the hardware is designed correctly, it may itself contain logic and rules to enter different power saving states. To enter these power saving states the hardware requires that there is no activity in the system, in other words, there is no task ready to be run by the OS kernel scheduling mechanism. Even if power saving functionality is implemented in the hardware, activating it might not always be possible. If the applications running on the hardware are "misbehaving", then the system will be active all of the time and this makes it impossible for the power saving features to be activated at hardware level. Some of these power saving features include: changing the clock frequency dynamically, supporting multiple operating voltages and switching integrated peripherals' sleep modes.

	Different parts of the hardware will require different amounts of power to run. The following pie diagram is not based on any real measurements but roughly shows how power consumption is distributed between different subsystems in a device:		Different parts of the hardware will require different amounts of power to run.
