摘要
Mobile is one of the most successful computing ecosystems to date. Driven by user demands, each device generation must compute faster, last longer, and accommodate more peripherals into increasingly thinner form factors. The talk describes how mobile devices evolved over the past decade to provide today's desktop-like interactive user experience while adhering to severe mobile power, thermal, and battery energy constraints. The findings, based on examining state-of-the-art mobile devices released over the past decade, coupled with a 25,000-application-based crowdsourcing user study, provide new insight into how hardware capabilities impact users' quality of experience (QoE). Mobile CPUs play a crucial role in achieving high user satisfaction by providing application responsiveness. However, sustaining conventional CPU performance-boosting techniques, such as aggressive out-of-order microarchitectures and multicore scaling, is becoming harder in the face of increasing power consumption. Enabling future mobile devices for the next "killer" application requires the industry to depart from conventional mobile CPU innovation techniques and embrace new approaches to achieve high QoE. Hardware customization and specialization along with solutions that reach for tighter integration between the hardware and software layers, must all be treated as first-class citizens in future mobile system design.To this end, the talk describes a new set of synergistic cross-layer solutions that effectively bridge the gap between user experience and mobile device compute capability.
BIO
Prof. Vijay Janapa Reddi is an Assistant Professor in the Department of Electrical and Computer Engineering at The University of Texas at Austin. His research interests include system architecture and software design and implementation to address performance, power, energy and reliability issues for mobile and high-performance computing systems. He is the recipient of the Intel Early Career Award and has received Best Paper and Top Picks awards in Computer Architecture. He is also very passionate about STEM education at an early age, particularly involving computer science, and is responsible for a new curriculum that focuses on teaching computer science to 6th graders in the Austin Independent School District, which ties directly into the heart of public education in Austin--Texas, through Arduino-based projects. He received his Ph.D. in Computer Science from Harvard University. Please see his webpage at http://users.ece.utexas.edu/~vjreddi/.
