  • Publication number: 20250004900
    Abstract: An image processing accelerator device includes a memory, a decoder circuit, an event monitor circuit and a filter control circuit. The memory receives a first command corresponding to a task, and a wait event command which follows the first command. The decoder circuit decodes the first command and the wait event command to determine a register to be accessed in an image processing circuit and first data to be written by the first command, and generates an event identifier. The event monitor circuit determines according to the event identifier whether the image processing circuit has finished executing the task, and accordingly controls the image processing circuit to execute a command corresponding to a next task. The filter control circuit records second data previously stored in the register, and writes the first data to the register when the first data is different from the second data.

  • Publication number: 20240320365
    Abstract: A data protection device includes a memory, a read-only memory and a verification circuit. The read-only memory stores first confidential data, and transmits the first confidential data to the memory after being powered up, wherein the first confidential data includes multiple groups of repetitive data and the groups of repetitive data are the same with one another. The verification data determines whether the first confidential data is valid before a processor reads the first confidential data from the memory, and allows the processor to read the first confidential data from the memory when the first confidential data is valid.

  • Patent number: 11775488
    Abstract: System, method, and various embodiments for providing a data access and recommendation system are described herein. An embodiment operates by identifying a column access of one or more data values of a first column of a plurality of columns of a table of a database during a sampling period. A count of how many of the one or more data values are accessed during the column access are recorded. A first counter is incremented by the count. The sampling period is determined to have expired. A load recommendation on how to load data values into the first column based on the first counter is computed. The load recommendation for implementation into the database for one or more subsequent column accesses is provided.

  • Patent number: 10558636
    Abstract: Disclosed herein are system, method, and computer program product embodiments for providing read queries latch-free access to an index page. In an embodiment, a processor receives a request from a read query to access one or more records of an index page. The index page includes an update pointer and a slot array. The processor locates one or more updates prepended to the index page by locating a most recently prepended update indicated by the update pointer. Then, the processor generates a local offset table with entries in the slot array and the located one or more updates. The generated local offset table enables the processor to provide the read query access to the one or more records of the index page.
