Modern computer technology has enabled us to realize IoT (Internet of Things), or IoE (Internet of Everything), where a lot of “Edge Computers” such as wearable/implantable devices or sensors are connected to servers through computer network. In the near future, edge computers will be required to have more intelligence to extract knowledge from collected data on site, and to operate with very limited electrical energy obtained by energy harvesting. Our lab is conducting research and development of VLSI design technology for ultra-low power CPU. Through collaborative project with other universities, we have developed a 32-bit CPU chip (see figures) whose internal computing circuits are powered-off in a very fine-grained manner. Measured results of the test chip demonstrated that energy consumption was reduced by 21-35% as compared to the conventional one. In addition, we are studying VLSI circuit techniques to enable robust operation at very low voltage (e.g. 0.2-0.3V), and energy-efficient computer architecture/circuit to combine power-off control and non-volatile memory technology.
