  • Publication number: 20230297157
    Abstract: Embodiments of a power consumption control apparatus, a processor, and a power consumption control method are disclosed, directed to improving accuracy of power consumption regulation. The power consumption control apparatus includes a constant-frequency clock generator and a power consumption regulator. The power consumption regulator is connected to one or more processing units in a system-on-a-chip. The constant-frequency clock generator provides a constant-frequency clock signal for the power consumption regulator. The power consumption regulator obtains power consumption caused by the one or more processing units in a period of time, and regulates current power consumption of the one or more processing units based on the power consumption.

  • Patent number: 11623210
    Abstract: A method for preparing a silicate/carbon composite from attapulgite, and use of the silicate/carbon composite are disclosed. The preparation method includes: (1) with attapulgite as a raw material, preparing SiO2 with a special structure; (2) dispersing the prepared SiO2 in water to obtain a suspension, and subjecting the suspension to ultrasonic dispersion; dissolving a metal nitrate in the suspension, adding NH4Cl, and adding ammonia water dropwise to the suspension; and adding sucrose to obtain a suspension; (3) subjecting the suspension to microwave hydrothermal reaction; after the reaction is completed, centrifuging a resulting system; and separating a resulting solid; and (4) subjecting the solid to high-temperature calcination in a muffle furnace, and grinding a resulting product to obtain the silicate/carbon composite, which can be used in photocatalytic ammonia synthesis.
