Patent number: 11740818Abstract: Techniques for performing compression operations on persistently-stored data blocks during read/write commands. A method embodiment performs in-line data compression operations over data blocks referenced by a caller. The in-line data compression operations are performed during execution of a storage input-output (I/O) command, between the event of receipt of the storage I/O command and the event of returning status of the storage I/O command. The storage I/O operation is associated with at least one data group comprising one or more data blocks that are identified by the caller. Upon receipt of the storage I/O command, one or more compression rules are applied to the data blocks to determine one or more compression parameters, which compression parameters are used to form specific compression operations that are performed over at least a portion of the data group. The status pertaining to the execution of the storage I/O operation is returned to the caller.Type: GrantFiled: August 26, 2020Date of Patent: August 29, 2023Assignee: Nutanix, Inc.Inventors: ChernYih Cheah, Kiran Tatiparthi, Manosiz Bhattacharyya, Varun Kumar Arora

Method for motion estimation, non-transitory computer-readable storage medium, and electronic device
Patent number: 11716438Abstract: A method for motion estimation, a non-transitory computer-readable storage medium, and an electronic device are provided. The method includes the following. An error between a block to be matched and each of reference blocks is determined to obtain multiple errors. At least one candidate block is determined from the reference blocks according to the multiple errors. A random number range is determined according to a displacement between the block to be matched and each of the reference blocks. Random motion vectors are obtained by using a motion vector between the block to be matched and each of the at least one candidate block as a basic motion vector and random numbers within the random number range as increments. A target motion vector corresponding to the block to be matched is determined according to the random motion vectors.Type: GrantFiled: March 29, 2021Date of Patent: August 1, 2023Assignee: GUANGDONG OPPO MOBILE TELECOMMUNICATIONS CORP., LTD.Inventor: Wenting Shu -

Patent number: 11709598Abstract: The over-provisioning (OP) of a physical storage device (PSD) may be increased, and the useful life of the PSD increased, by converting uncompressed data stored on the PSD to compressed data. It may be determined that increasing the useful life of the PSD, and the data reduction resulting from the compression, outweigh the benefit of faster I/O response times if the data remains uncompressed. A first portion of the PSD may be initially reserved for compression. A second portion of the PSD may store compressed data. It may be determined whether it is desirable to increase the OP of the PSD to thereby reduce the effective write rate on the PSD. If compression is determined to be desirable, the dynamic portion may be compressed, thereby reducing the amount of storage space consumed by the data, and freeing up storage space that can be used by the PSD for OP.Type: GrantFiled: September 21, 2020Date of Patent: July 25, 2023Assignee: EMC IP Holding Company LLCInventors: Dustin H.
