Abstract:
We experience a major form-factor shift in electronic systems every 10 to 15 years. The most recent examples are the mobile platforms powered by heterogeneous system-on-chips (SoCs), while the next one is yet to dominate the market. Despite their impressive performance, mobile platforms still suffer from tight thermal constraints and resulting power consumption limitations. Furthermore, the complexity of current designs surpasses our ability to control the power management knobs optimally. The first part of this talk will overview a few recent results on the modeling, analyzing, and optimizing power-temperature dynamics of multiprocessor SoCs. The second part will overview "Systems-on-Polymer" as a candidate technology to drive the next wave of computing. This approach has recently been introduced to combine the advantages of flexible and traditional silicon technologies. We will present optimal energy harvesting and management techniques using flexible materials for energy-neutral edge devices. These devices will be illustrated using edge-AI applications, including mmWave-based rehabilitation, gait analysis, and activity recognition.
