Contribution to Automated Generating of System Power-Management Specification

Nowadays, the electronic system design is constrained by several factors. One of them is the system power consumption, since many devices have limited energy source (e.g. Internet of Things sensor devices) - they run on batteries or are powered by energy harvesting from environment. The so-called power management is usually adopted during system design to minimize power consumption of the system under development, which enables to apply very popular power-reduction techniques, such as clock gating, power gating, or voltage and frequency scaling. The specification of power management is not an easy task, and therefore in our previous work, we have proposed a simplification method by increasing abstraction and automation of the design process. In this paper, we are taking the design automation one more step forward by proposal of a method that enables automated specification of system power management using the system architecture and abstract simulation results. The automatically generated power management can reduce the power by tens of percent as showed by the experiments.
