Fundamentals of Low Power Design using Intel Atom Processor
Low power design means different things based on the type of application that you are developing. Applications that operate in energy starved environments may need to rely on energy harvesting techniques to extract energy from their surroundings while they perform only simple functions.
Applications that can carry their energy supply within them need to remain frugal with how they spend their energy budget while they perform moderate types of processing. Applications that are permanently attached to a wall socket may have the luxury of being able to perform the highest complexity processing, but they still need to address how they use that energy to ensure the highest compute-per-unit-of-energy density while avoiding generating too much heat.
While the specific constraints that a developer for each type of low power application needs to address may differ, the techniques and strategies for developing those applications across the entire low power spectrum are similar. In this "Fundamentals of Low Power Design", we will first explore the concepts of energy consumption and identify the different points along the spectrum of low power designs. We will then explore the hardware and software techniques that are available to developers using microprocessors.
The course will wrap up by applying the material presented in the first part of the course to low power designs using the Intel Atom processor. The course includes numerous links to specific resources that explain how to take advantage of the Atom's resources that enable developers to extract the most performance per unit of energy.
