  • Publication number: 20240035844
    Abstract: Aspects concern a method for correcting errors in map data comprising obtaining map data specifying travel possibilities between locations, generating a routing graph from the map data by assigning a vertex to each location and an edge from one vertex to another vertex if the map data specifies that it is possible to travel from the location to which the first vertex is assigned to the location to which the second vertex is assigned, identifying the largest strongly connected component of the routing graph, identifying one or more further strongly connected components of the routing graph, detecting errors in the map data by identifying travel possibilities that are not in the map data which lead to missing connections between the one or more further strongly connected components of the routing graph and the largest strongly connected component of the routing graph and amending the map data by the identified travel possibilities.

  • Patent number: 11467764
    Abstract: A non-volatile memory express (NVMe)-based data read method, apparatus, and system are provided. In various embodiments, a read instruction can be triggered by a host. The read instruction carries indication information of a first address opened by the host to an NVMe controller for addressing and accessing. In those embodiments, the host after obtaining the read instruction can send a data packet to the host. The data packet carries the first address and payload data. Still in those embodiments, the host can, after receiving the data packet, determine a second address based on the first address, and store the payload data into storage space indicated by the second address. The second address may be a private memory address of the host. Because a relationship between the second address and a communication protocol is broken, and the host may access the second address without being restricted by the communication protocol.
