Dynamic Thermal Management for Homogeneous Embedded Multicore Processors: Thermal Modeling, System Environment, and Measurement Results
Axel Sikora, Sebouh Toumassian · International Journal of Computer and Electrical Engineering · 2015
The increasing number of transistors being clocked at high frequencies of modern microprocessors lead to an increasing power consumption, which calls for an active dynamic thermal management.In a research project a system environment has been developed, which includes thermal modeling of the microprocessor in the board system, a software environment to control the characteristics of the system's timing behavior, and a modified Linux scheduler, which is enhanced with a prediction controller.Measurement results are shown for this development for a Freescale i.MX6Q quad-core microprocessor.
