This e-book introduces software program Thermal administration (STM) as a method of decreasing strength intake in a computing procedure so that it will deal with warmth, increase part reliability and elevate method protection. Readers will reap the benefits of this pragmatic consultant to the sector of STM for embedded platforms and its catalog of software program strength administration recommendations. because thermal administration is a key bottleneck in embedded structures layout, this publication specializes in root reason for warmth in embedded platforms: energy. considering software program has a tremendous impression on energy intake in an embedded procedure, this ebook urges software program engineers to control warmth successfully by means of figuring out, categorizing and constructing new how you can lessen static and dynamic energy intake. while such a lot books on thermal administration describe mechanisms to take away warmth, this publication makes a speciality of methods for software program engineers to prevent producing warmth within the first place.

Example text

The larger the difference, the faster heat will flow, until the point at which thermal equilibrium is reached and both bodies are of equal temperature. See Fig. 3. The effect described in the Zeroth Law is what makes a thermometer useful. Suppose you stick a room-temperature thermometer into boiling water. Heat will flow from the boiling water into the thermometer until they are the same temperature. When they are both the same temperature, heat stops flowing between them, so the temperature of the thermometer stops rising.

The aim of the field of Software Thermal Management is to encourage software engineers to play a more active and central role in the task of managing the thermal performance of embedded systems. Summary • The field of STM sits at the intersection of Thermodynamics, Electrical Engineering, and Software Engineering. The field of Software Thermal Management is similar to the concept of software power management, except that it is narrower in scope, and focuses on thermal performance of the system instead of broadly looking at system-wide power draw.

The technical reference manual for the TI OMAP4470, for instance, is 5,000+ pages. With this much information and levels of configuration within the processor, it’s nearly impossible to make a quantitative determination with high certainty that a given processor will meet the thermal requirements of the system. If thermal performance will be an important issue for a given design, here are some key questions to ask when selecting a processor: 1. How low can the processor go (power draw) while in an idle state?
