  • Publication number: 20250085894
    Abstract: A storage device manages memory use data, such as map data which the storage device manages using a host memory, as journal data in a buffer memory located inside the storage device in a low power mode. The memory use data may be managed by updating journal data during the low power mode, and a command of a host device may be processed by updated journal data after switching from a low power mode to an active mode.

  • Patent number: 12225222
    Abstract: The present invention relates to an image encoding/decoding method and device. The image decoding method according to the present invention comprises the steps of: decoding a prediction mode index; determining whether the prediction mode index indicates function-based intra prediction; inducing a parameter (s) for generating a function, when the prediction mode index indicates the function-based intra prediction; generating the function on the basis of the induced parameter (s); and performing intra prediction by using the generated function.
