Portable Platforms for Telecommunication, Security, and Biomedical Applications

Our research tackles technical challenges associated with improving energy efficiency and reusability of battery-powered system-on-chip portable platforms. Improving energy efficiency of portable platforms increases their operational sustainability, while improving their reusability increases their cost-effectiveness. Improving energy efficiency, however, inevitably worsens reusability and vice versa. To effectively address such a conflict, we take an application-centric approach, providing for high energy efficiency through sufficient application-driven platform specialization, while supporting needed reusability through sufficient application-aware platform flexibility. We pursue the following three lines of inquiry:
  • Energy-efficient programmable architectures for the application domains of short-range wireless communication, attack-resistant asymmetric cryptography, and biomedical ultrasound imaging, with the goal to enable flexible and efficient application execution;

  • Robust analytical models of nonlinear dynamics of the platform energy supply and demand, with the goal to enable model-predictive automatic optimization of the platform operation during application execution;

  • Low-complexity optimization algorithms that automatically determine the optimal or near-optimal settings for programmable platform parameters per given application requirements, with the goal to maximize platform performance (subject to battery-imposed energy constraints) or minimize energy consumption (subject to application-imposed performance constraints) during application execution.
