Mobile computing is experiencing a technological renaissance, and the Web is Florence. Throughout the past decade, the Web has redefined the way people retrieve information, communicate with one another, and extract insights. Although rife with opportunity, the energy-constrained nature of mobile devices is a major roadblock to the potential that next-generation Web technologies promise.
In this talk, I will show a path for achieving an energy-efficient mobile Web by rethinking the conventional abstractions across the hardware/software interface along with deep introspection of Web domain knowledge. In particular, I will describe an energy-efficient mobile processor architecture specialized for Web technologies as well as programming language support that empowers Web developers to make calculated trade-offs between energy-efficiency and end-user quality-of-service. Together, they form the core of my hardware-software co-design philosophy toward the next major milestone of the Web evolution: the Watt-Wise Web. As computing systems in the Internet-of-things era increasingly rely on fundamental Web technologies while operating under even more stringent energy constraints, Watt-Wise Web is here to stay.
