Abstract: Systems and methods of analyzing on-shelf price tag labels and products at a product storage facility include an image capture device that captures one or more images of one or more product storage structures at a product storage facility. A computing device communicatively coupled to the image capture device analyzes the images of the product storage structures captured by the image capture device and detects individual price tag labels and individual products located on the product storage structure. Based on the detection of the price tag labels and the products, the computing device also defines separate product storage spaces of the product storage structure, determines which price tag labels are allocated to which of the separate product storage spaces, and associates in a database the price tag labels allocated to the product storage spaces with the products stored in those product storage spaces.

Abstract: Systems and methods of monitoring inventory of a product storage facility include an image capture device configured to move about the product storage areas of the product storage facility and capture images of the product storage areas from various angles. A computing device coupled to the image capture device obtains the images of the product storage areas captured by the image capture device and processes the obtained images of the product storage areas to detect individual products captured in the obtained images. Based on detection of the individual products captured in the images, the computing device analyzes each of the obtained images to detect one or more adjacent product storage structures (shelves, pallets, etc.) and identifies and selects a single image that fully shows a product storage structure of interest and fully shows each of the products stored on the product storage structure of interest.

Abstract: A memory management system and method are described. In one embodiment, a memory management system includes a memory management unit for virtualizing context memory storage and independently controlling access to the context memory without interference from other engine activities.

Abstract: A memory access technique, in accordance with one embodiment of the present invention, includes caching page size data for use in accessing a set-associative translation lookaside buffer (TLB). The technique utilizes a translation lookaside buffer data structure that includes a page size table and a translation lookaside buffer. Upon receipt of a memory access request a page size is looked-up in the page size table utilizing the page directory index in the virtual address. A set index is calculated utilizing the page size. A given set of entries is then looked-up in the translation lookaside buffer utilizing the set index. The virtual address is compared to each TLB entry in the given set. If the comparison results in a TLB hit, the physical address is received from the matching TLB entry.

Abstract: A memory access technique, in accordance with one embodiment of the present invention, includes caching segmentation data. The technique utilizes a separate memory for storing a plurality of context specifiers and an MMU. The MMU includes an on-chip cache and a segmentation unit. The MMU receives a location of a particular context specifier and a corresponding context index for each of one or more of the plurality of context specifiers stored in the separate memory. The segmentation unit retrieves the particular context specifier and caches it locally. The segmentation unit also binds the cache location of the particular context specifier to the corresponding context index. After caching one or more context specifiers and generating a corresponding binding, the segmentation unit may receive a memory access request that includes a given context index. A given context specifier that is cached locally is accessed by the segmentation unit using the context index to get a base address.
