  • Patent number: 10999061
    Abstract: Aspects of the disclosure provide methods and apparatuses for storing service data. In some examples, an apparatus for storing service data includes processing circuitry. The processing circuitry receives service data of a user and determines, in a plurality of blockchains, a target blockchain according to a user attribute of the user. Based on the service data and an eigenvalue of a block header of a first block in the target blockchain, the processing circuitry generates a second block in the target blockchain. The first block is a previous block of the second block. The second block is used for recording the service data.

  • Patent number: 10834352
    Abstract: An image sensor has an array of pixels configured in multiple blocks; each block coupled to a separate analog-to-digital converter (ADC) to provide digitized image data. The ADCs feed digitized images into an image RAM; and the image RAM feeds digitized images to an alignment buffer in a first pixel order. The alignment buffer provides digitized images to an image processor in a second pixel order different from the first pixel order. In an embodiment, the alignment buffer uses a multiport RAM. In another embodiment, the alignment buffer uses first and second alignment buffer RAMs, writing one alignment buffer RAM while reading the other alignment buffer RAM to provide image data to the image processor. In embodiments, the alignment buffer provides digitized images in an order selectable between a full resolution and a reduced resolution order, and selectable between a right-to-left and left-to-right order.

  • Patent number: 10672101
    Abstract: A bond-per-pixel-block image sensor has a pixel array including multiple pixel blocks with selection circuitry to couple signals to an ADC. The image sensor has an image RAM of DRAM superblocks, each superblock with multiple DRAM blocks each having tristate output driving an image RAM output bus, and data input from several of the ADCs. Each DRAM block has an address multiplexor coupled to read and write addresses. DRAM blocks of each superblock are written simultaneously with data wider than a width of the image RAM output bus. A method of capturing and processing images includes reading a first image frame from pixels of a pixel block through ADCs; writing digital pixel data for the first image frame in a first DRAM superblock; and reading pixel data into an alignment buffer. The method includes overlapping reading the first image frame with writing a second image frame into a second superblock.

    Abstract: An apparatus including processing circuitry and a method are described. When receiving a cross-chain transaction request to transfer a resource from a first account to a second account, the processing circuitry is configured to generate a task corresponding to the first account. The task can indicate conditions for implementing events in transferring the resource. A first blockchain system provides services for the first account, and a second blockchain system different from the first blockchain system provides services for the second account. The processing circuitry transfers the resource to the second account based on the task when a first plurality of first nodes in the first blockchain system reaches a consensus on a generation event of the task and updates a task status of the task to being finished when a plurality of second nodes in the second blockchain system reaches a consensus on a transfer event of the resource.
