Abstract: A device comprises: a classical computing device; a quantum computing device; a memory for storing one or more programs; and a processor communicating with the memory to execute the one or more programs and control the classical computing device and the quantum computing device. The processor may: obtain the boundary condition and respective initial values of a plurality of points of a geometric structure with respect to an object, by means of the classical computing device; obtain solutions to respective multi-physics problems of the plurality of points on the basis of the obtained boundary condition and respective initial values of the plurality of points, by means of the quantum computing device; and map the obtained solutions to the multi-physics problems to respective plurality of points by means of the classical computing device.

Abstract: A low-power speech recognition device based on artificial intelligence and a method of operating the same are proposed. The method including: receiving an audio signal; storing the audio signal in a memory; detecting whether the audio signal is a speech signal spoken by a user; preprocessing, by an audio processor, noise and an echo in the audio signal stored in the memory, when the audio signal is the speech signal; determining, by the audio processor, whether the preprocessed audio signal contains an activation word; activating a processor for natural language processing, when the preprocessed audio signal contains the activation word; and performing, by the processor, natural language processing on the audio signal received after the audio signal containing the activation word. Accordingly, the device uses an artificial intelligence technology while power consumption is reduced, thereby satisfying industrial and user demands for producing and using low-power products.
