Publication number: 20250004900Abstract: 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.Type: ApplicationFiled: May 6, 2024Publication date: January 2, 2025Inventors: Jiang-He XU, Qin-Wei SHE, Yan-Xiong WU

Patent number: 11775488Abstract: 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.Type: GrantFiled: March 21, 2022Date of Patent: October 3, 2023Assignee: SAP SEInventors: Panfeng Zhou, Vivek Kandiyanallur, Colin Florendo, Robert Schulze, Zheng-Wei She, Yanhong Wang, Amarnadh Sai Eluri

Patent number: 10558636Abstract: 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.Type: GrantFiled: April 27, 2016Date of Patent: February 11, 2020Assignee: SAP SEInventors: Zheng-wei She, Xu-dong Qian, Zhi-ping Xiong
