Abstract: An integrated circuit (IC) comprises an array of power base units (PBUs) organized in rows and columns. The IC further includes an array-level power accumulator that includes a power estimation unit (PEU) and two or more column power accumulators (CPAs) coupled with the PEU and the PBUs via dedicated wiring. Additionally, a power clock management controller (PCMC) is linked to the array-level power accumulator. Notably, some CPAs are connected to the array-level power accumulator through dedicated wiring.

Abstract: Provided are an AR translation processing method and an electronic device, which relate to the technical field of communications. By the method, in a scenario in which an electronic device is used for AR translation, a pose change of the electronic device can be detected in real time, and feature matching can be performed on a plurality of consecutive frames of images acquired by a camera, so that whether to-be-translated text needs to be fully translated or partially translated, or needs not to be translated can be determined based on the pose change of the electronic device and a feature matching result, and therefore a corresponding translation trigger strategy is selected. In this way, repeated translation can be effectively avoided, thereby saving computing resources in the AR translation process and improving the translation efficiency to a particular extent.

Abstract: A first frame of time of flight (TOF) data including projection off data and infrared data is obtained, and after determining that a data block satisfying that a number of data points with values greater than a first threshold is greater than a second threshold is present in the infrared data, TOF data for generating a first frame of a TOF image is obtained based on a difference between the infrared data and the projection off data. Because the data block satisfying the number of data points with values greater than the first threshold is greater than the second threshold is an overexposed data block, and the projection off data is TOF data acquired by a TOF camera with a TOF light source being off, the difference between the infrared data and the projection off data can correct the overexposure, improving quality of the first frame of the TOF image.

Abstract: This application provides a data processing method and an apparatus. The data processing method includes: acquiring a first frame of time-of-flight (TOF) data; processing the first frame of TOF data into a TOF image; and performing face recognition by using the first frame of TOF image to obtain a recognition result. When TOF data is used for face recognition, higher security can be achieved. In addition, the first frame of TOF image is used for face recognition immediately after the first frame of TOF image is obtained, so that the execution speed is high. Because the TOF data is less affected by light, a high-quality TOF image can be obtained even if the first frame of TOF data is used, and therefore, the recognition accuracy is high.

Abstract: Embodiments of this application provide a face recognition method and apparatus, including: obtaining TOF data; processing the TOF data into a TOF image in a TEE; and performing face recognition by using the TOF image, to obtain a recognition result. Because the TOF data is used for face recognition, higher security is achieved. Implementation in the TEE can further improve the security.

Abstract: A processor IC has multiple power base units (PBUs), arranged in an array. Each PBU includes a switch, a memory unit and a compute unit. It further includes a power estimator for the switch, memory unit, and compute unit. The PBUs communicate with an array-level power accumulator via dedicated wiring. Communication via the dedicated wiring may use timestamps to ensure time-accurate aggregate estimates. The switch power estimator estimates dissipation based on port activity. The memory power estimator estimates dissipation based on read and write activity and bit toggling in the memory. The compute power estimator estimates power based on monitoring input data zero values, bit toggling, instruction type, and activity of reconfigurable processing units. The array-level power accumulator calculates the array-level nominal dynamic power estimate. A power clock management controller scales the dynamic power estimate for the actual clock frequency and measured supply voltage, and adds a static power estimate.

Abstract: Provided are a direct time of flight (dTOF) sensing module, a terminal device, and a ranging method, to resolve a problem that in a conventional technology, a dTOF sensing module cannot adapt to different detection scenarios to some extent. Every K light sensitive units (401) of W light sensitive units (401) included in the dTOF sensing module share a first storage space. A processing control unit (403) is configured to control gating of N light sensitive units (401). The gated N light sensitive units (401) occupy the first storage space, and Q time slice bins are allocated to each gated light sensitive unit (401), so that the dTOF sensing module operates in a first mode or a second mode. The dTOF sensing module is flexibly applicable to different detection scenarios.
