New Device Could Greatly Improve Speech and Image Recognition

Researchers have successfully demonstrated pattern recognition using a magnonic holographic memory device, a development that could greatly improve speech and image recognition hardware. They built a prototype eight-terminal device consisting of a magnetic matrix with micro-antennas to excite and detect the spin waves. It takes about 100 nanoseconds for recognition, which is the time required for spin waves to propagate and to create the interference pattern. The main challenge is the scaling of the operational wavelength, which requires the development of sub-micrometer scale elements for spin wave generation and detection.

The story is too old to be commented.
