The execution of software has a significant impact on various runtime characteristics of the hardware. Software critically influences energy consumption, thermal development, or the electromagnetic behavior of a CPU/MCU. While EMC analyses can be used for side-channel attacks, critical temperature patterns and LoadJumps or PowerPeaks can lead to malfuncitons. The new topic "Optimization of processor power characteristics in software" shall be dedicated to the avoidance of LoadJumps and PowerPeaks.
