Battery operated devices require frequent recharging or changing of batteries due to high energy usuage, e.g. smart phones, IoT sensors. There is also high costs of operation for energy demanding applications due to high energy usage, e.g. servers and data centers.

GreenOS is a software that is installed on the operating system (run-time operation) that automatically allocates computing resources efficiently. Key advantages include energy savings (>30%) and simple implementation. It has been tested on ARM multicore systems.

Comparison with other methods:

• Dynamic Voltage-Frequency Scaling provides limited amount of energy savings
• Turbo-Boosting (Extending idle periods) has higher power consumption during active phase due to higher frequency and voltage
• Multicore Processor Heterogeneity maintains constant performance and therefore offers limited savings in energy

We are looking to connect with:

• Companies manufacturing battery operated devices, eg. Smartphones, sensors, etc.
• Companies manufacturing equipment/software for data centers

We are seeking collaboration partners to perform pilot testing with GreenOS.
