Microcontroller Energy Management System

Summary

Researchers at Purdue University have developed a technology that utilizes two different forms of Random Access Memory (RAM) that increases performance and decreases energy usage simultaneously. By combining the efficient, unreliable Static Random Access Memory (SRAM) with the inefficient, reliable Ferroelectric Random Access Memory (FRAM), a new hybrid model was developed. This hybrid, combined with several built-in techniques to optimize the system, experimentally demonstrated a performance boost of up to two times and decreased energy usage of up to 20 percent over a high quality FRAM-based model. This could be used as a basis for improving performance in low power devices powered by energy harvesting sources.
