  • Publication number: 20230195477
    Abstract: A computing system includes a host device and a root of trust (RoT) device for performing batch encryption and decryption operations facilitated by a direct memory access (DMA) engine. The host device generates a command table for batch processing of a set of address tables that each describe a set of data blocks of a file to be encrypted or decrypted. The DMA engine facilitates a DMA transfer of the command table from the host memory to an RoT memory of the RoT device. The RoT device then performs batch processing of the address tables referenced in the command table. For each address table, the DMA engine copies a set of data blocks from the host memory to the RoT memory, a cryptographic engine encrypts or decrypts the data blocks, and the DMA engine copies the transformed data blocks back to the host memory.

  • Publication number: 20230185745
    Abstract: A DMA system includes two or more DMA engines that facilitate transfers of data through a shared memory. The DMA engines may operate independently of each other and with different throughputs. A data flow control module controls data flow through the shared memory by tracking status information of data blocks in the shared memory. The data flow control module updates the status information in response to read and write operations to indicate whether each block includes valid data that has not yet been read or if the block has been read and is available for writing. The data flow control module shares the status information with the DMA engines via a side-channel interface to enable the DMA engines to determine which block to write to or read from.

  • Publication number: 20210396628
    Abstract: The present invention provides an apparatus for collecting and detecting liquid samples comprising a first chamber and a second chamber. The first chamber is used for collecting liquid samples for initial detection, and the second chamber is used for collecting liquid samples for second confirmatory detection. The first chamber and second chamber of the apparatus are detachable. When a second confirmatory detection is necessary, the second chamber can be separated from the first chamber, and then sent to a detection agency for confirmatory detection. It can avoid the contamination of liquid samples caused by contacting with test strip of a traditional apparatus; thus, it can effectively reduce the space required for storing liquid samples and greatly reduce the risk of leakage of liquid sampled during transportation.

  • Patent number: 11051227
    Abstract: Embodiments for a method for enhancing communication for operating along with a plurality of cooperating communication enhancement modules are disclosed. The communication enhancement module receives a STANAG 4586 message from an upstream module and determine whether a point-to-point wireless connection is available to the destination. If a point-to-point wireless connection is available, the module sends a message over the point-to-point wireless connection to the destination. If a point-to-point wireless connection is not available, the module identifies a multi-hop path to the destination via at least one other communication enhancement module, modifies the STANAG 4586 message to create a modified message having a format corresponding to the communication enhancement modules, and send the modified message to a next hop communication enhancement module on the multi-hop path for directing toward the destination.
