  • Publication number: 20240061780
    Abstract: A computer-implemented method for allocating memory bandwidth of multiple CPU cores in a server includes: receiving an access request to a last level cache (LLC) shared by the multiple CPU cores in the server, the access request being sent from a core with a private cache holding copies of frequently accessed data from a memory; determining whether the access request is an LLC hit or an LLC miss; and controlling a memory bandwidth controller based on the determination. The memory bandwidth controller performs a memory bandwidth throttling to control a request rate between the private cache and the last level cache. The LLC hit of the access request causes the memory bandwidth throttling initiated by the memory bandwidth controller to be disabled and the LLC miss of the access request causes the memory bandwidth throttling initiated by the memory bandwidth controller to be enabled.

  • Publication number: 20240045809
    Abstract: The present application discloses a computing system and an associated method. The computing system includes a memory, a master computing device and a slave computing device. The master computing device includes a memory controller and an input-output memory management unit (IOMMU). When the slave computing device accesses a first virtual address, and a first translation lookaside buffer (TLB) of the slave computing device does not store the first virtual address, the first TLB sends a translation request to the IOMMU. The IOMMU traverses page tables of the memory controller to obtain a first physical address corresponding to the first virtual address, selects and clears a first virtual address entry from a second TLB of the computing system according to a recent use time and a dependent workload of each virtual address entry to store the first virtual address and the first physical address.

  • Patent number: 11868394
    Abstract: Methods, apparatuses, and embodiments related to analyzing the content of digital images. A computer extracts multiple sets of visual features, which can be keypoints, based on an image of a selected object. Each of the multiple sets of visual features is extracted by a different visual feature extractor. The computer further extracts a visual word count vector based on the image of the selected object. An image query is executed based on the extracted visual features and the extracted visual word count vector to identify one or more candidate template objects of which the selected object may be an instance. When multiple candidate template objects are identified, a matching algorithm compares the selected object with the candidate template objects to determine a particular candidate template of which the selected object is an instance.
