Abstract: A computing circuit with a de-identified architecture, a data computing method, a data processing system, and a data de-identification method are provided. The computing circuit includes an arithmetic array and a de-identification circuit. The computing circuit may perform an accumulation operation on input data to generate accumulated data by the arithmetic array. The de-identification circuit has an analog offset error determined based on an analog physical unclonable function. The computing circuit may operate the accumulated data according to the analog offset error to generate de-identification data by the de-identification circuit. It can not only provide the analog offset error through the transistors in the de-identification circuit, but also be combined with obfuscated code settings to dynamically adjusting the degree of de-identification of data.

Abstract: Disclosed is a device for preparing a silicon carbide crystal including a crucible and a crystal expansion guide assembly. The crucible includes a crucible body and a crucible cover fixing a seed and covering the crucible body. The crystal expansion guide assembly includes a frame member and a tubular core member. The frame member is fixed to the crucible body, located between the crucible cover and a raw material accommodated in the crucible body, and provided with a through hole with a diameter greater than a diameter of a growth surface of the seed. The tubular core member is mechanically connected to an inner wall of the through hole. During a crystal growth process, the tubular core member falls off due to contact with a growth front of a crystal. The frame member does not react with the crystal. Thus, a large-sized crystal ingot with high quality can be obtained.
