Abstract: An energy-efficient assignment of a task set T to a group of M processing devices models the process of deciding the assignment as a combinatorial optimization problem having an objective function optimizing the power consumption of the devices when executing subsets of the tasks, under a constraint that the total utilization of the task subset assigned to each respective processing device is lower than a threshold depending on the number of its processor cores. The objective function may be: min ? ? i = 1 M P i ( ? i ) , where ?i denotes the subset of tasks allocated to the ith device, and Pi(?i) represents power consumption of the ith device when executing ?i, and the constraint U?i?Mi/4 for all the devices, where U?i is the total utilization of ?i executing on the ith device, and Mi denotes the number of cores of the ith device. Solving the problem using a MaxMin or genetic algorithm gives good energy efficiency.

Abstract: The present disclosure provides computer-implemented methods, systems, and devices for controlling an external shared clock in a computing system with a plurality of system on a chips (SoCs). To do so, while a first SoC is in a low power mode, the second SoC receives a wake-up input that causes the second SoC to exit a low power mode. The second SoC asserts a clock request signal line to activate an external shared clock. The clock control system determines a state associated with the external shared clock, wherein the external shared clock is external to the first SoC. The clock control system, in accordance with a determination that the external shared clock is in an off state, transmits a signal to the external shared clock to cause the external shared clock to enter a startup state and begin producing a shared clock signal.
