Abstract - Machine Learning for Performance and Power Modeling/Prediction:
Estimating the power and thermal characteristics of a processor is essential for designing its power delivery system, packaging, cooling, and power/thermal management schemes. Power models that estimate the power consumption of each functional unit/hardware component from first principles are slow and tedious to build. Machine learning can be used to create power models that are fast and reasonably accurate. Machine learning can also be used to calibrate analytical models that estimate power. In this talk, I’ll present some examples of performance and power modeling using machine learning.
Another application for machine learning has been to create max power stressmarks. Manually developing and tuning so called stressmarks is extremely tedious and time-consuming while requiring an intimate understanding of the processor. In our past research, we created a framework that uses machine learning for the automated generation of stressmarks. In this talk, the methodology of the creation of automatic stressmarks will be explained. Experiments on multiple platforms validating the proposed approach will be described.
Yet another application for machine learning is in cross-platform performance and power prediction. If one model is slow to run real-world benchmarks/workloads, is it possible to predict/estimate the performance/power by using runs on another platform? Are there correlations that can be exploited using machine learning to make cross-platform performance and power predictions? A methodology to perform cross-platform performance/power predictions will be presented in this talk.

Abstract - Ultra Low Energy Computation Methods for Implantable Cardiac Devices:
The next generation implantable cardia devices are expected to evolve into smart connected devices, in sync with the ubiquitous trend of smart appliances. However, the path to future smart cardiac devices has major challenges that must be addressed. The nature of the application inherently makes the cardiac devices extremely resource constrained with mission critical functional specifications that must be met. Power consumption and functional reliability are the primary factors that govern the design of a cardiac device’s system architecture. Although existing low-power design techniques are efficient and are regularly utilized in modern cardiac devices to meet those goals, they fall short when it comes to solving the computational challenges anticipated in a smart and connected cardiac device. Our research aims to develop ultra-low energy computation methods and design methodologies that can enable future cardiac devices to become a reality. By analyzing the existing and the anticipated new computational workloads of a smart cardiac device, innovative and scalable power-saving design techniques are presented.
