System architectures
The power/performance response of mobile device is among the key factors to determine the commercial success of products such as modern high end smartphones. Since the introduction of the big.LITTLE architecture, Arm Ltd has been in the frontline to propose architectural solutions which allow partners to compete on the market with products which give great performance without compromising battery life. Despite advanced architectural solutions, the best results cannot be achieved without a properly designed software support spanning all the stack, from a rich Operating System like Linux all the way up to advanced run-times like Android and ChromeOS.
Since few years, the Arm’s Power Team is working with the open source community to enhance the general purpose Linux scheduler to more efficiently map tasks onto compute elements, running them at the appropriate voltage and frequency, so as to minimise energy consumption whilst ensuring that UI deadlines are met. This talk will give an overall view on the main challenges, related to power and performance optimization of Linux/Android mobile devices. The main components of the Energy Aware Linux scheduler will be introduced as well as the integration with the Android run-time.
The presentation will also briefly introduce the company and will provide pointers to few internship and job positions available for candidates interested in working in Arm.
