  • Publication number: 20240118893
    Abstract: This application relates to a pulse modulation control system, device, and method. The system includes a processor based on a RISC-V open-source instruction set architecture and a pulse modulation interface module. The processor is configured to receive an operation instruction of a user, and generate a data signal based on the operation instruction. The pulse modulation interface module is connected to the processor, and is configured to receive the data signal and output a preset waveform based on the data signal. Based on the RISC-V open-source instruction set architecture, the user may customize operations, which improves efficiency and flexibility of a pulse modulation process, and optimizes power consumption.

  • Publication number: 20230367976
    Abstract: Computer-implemented methods, apparatuses, and computer-readable media for model training and text processing are disclosed. In an example, an original text, a positive sample, and a negative sample are obtained. The positive sample and the negative sample are rewritten texts of the original text. A first, second, and third distribution parameter corresponding to the original text, the positive sample, and the negative sample, respectively, are determined by using an encoder. The first, second, and third distribution parameter are used to describe a first, second, and third semantic distribution, respectively. A model parameter of the encoder is optimized by using a loss function based on the first, second, and third distribution parameter. The loss function includes a first term that is used to constrain a degree of similarity between the first and second semantic distribution to be higher than a degree of similarity between the first and the third semantic distribution.

  • Patent number: 9727972
    Abstract: A method for generating a thumbnail of an image, includes: filtering an image to obtain an edge intensity value for each pixel point in the image; sliding a preset rectangular box on the image to perform a search and, at each searched position, calculating a distribution value of information amount in the rectangular box according to the edge intensity values of the pixel points therein; and selecting the rectangular box with the largest distribution value of information amount, and intercepting content of the image corresponding to the selected rectangular box to obtain a thumbnail of the image.

  • Publication number: 20160132559
    Abstract: Provided are a TCAM-based table query processing method and apparatus. The method includes: executing a first query process for querying a TCAM entry; while the first query process is executed, executing a second query process for querying one or more entries other than the TCAM entry, wherein the first query process and the second query process run independently of each other; and respectively acquiring a first query result and a second query result through the first query process and the second query process. The technical solution solves the technical problem in the related technologies that the packet processing time is long due to the TCAM-based table query manner and the packet forwarding performance is affected accordingly, shortens the packet processing time and improves the packet forwarding performance.

  • Publication number: 20160124862
    Abstract: Provides are a method and device for storing a direct table. The method includes that: it is determined that an internal table entry storage space of a chip is exhausted; a plurality of table entries of a direct table is stored in an internal statistics storage space of the chip, wherein the direct table can be directly accessed via a storage medium. The disclosure solves the problem of degraded forwarding performance caused by modes of storing the table entry in the prior art, and improves the forwarding performance.
