Brainmorphic Computing Hardware



We will develop a brainmorphic computing hardware, which realizes the brain-specific functions such as conscious/sub-conscious process, self, selective attention, and so on, by directly using inherent physics and dynamics of constituent devices. The resulting hardware would be small, efficient, high-performance. Some examples include the chaotic neural network reservoir, optimization through high-dimensional complex dynamics, and neural network composed of spin-orbit torque nano-devices.
The resulting hardware is suitable for the edge AI which learns users’ personal behavior. Examples include watching service devices embedded in hearing aids or dental implants, which monitor and learn personal cardiac and brain-wave signals or saliva ingredients, to detect abnormal situations.
