Abstract: A flash medium access method, including selecting, by a controller, a target function queue from N function queues according to a predefined rule, where the target function queue is a non-empty queue, a flash medium in which a die associated with the target function queue is located is in an idle state, obtaining a basic instruction from the target function queue, determining, according to preset queue mapping information, the die associated with the target function queue, where the controller is connected to at least one flash medium, and the queue mapping information indicates that the N function queues are in a one-to-one mapping relationship with the N dies, generating, according to a preset signal generation rule, a time sequence signal corresponding to the basic instruction, and sending the time sequence signal to the flash medium in which the associated die is located.

Abstract: This application relates to the field of communications technologies, and in particular, to a profile download technology. In a profile download method, a primary device obtains an embedded integrated circuit card identifier (EID) of a secondary device, where the EID is used by the primary device to obtain, from a mobile operator server, profile download information that matches the EID; receives the profile download information from the mobile operator server; and sends the profile download information to the secondary device, where the profile download information is used by the secondary device to download a profile from a profile management server, and the profile is installed in an embedded UICC (eUICC) of the secondary device after the download is complete.

Abstract: A cache coherence management method, a node controller, and a multiprocessor system that includes a first table, a second table, a node controller, and at least two nodes, where the node controller determines, in the first table according to address information of data, a first entry, where the first entry includes a first field and a second field. The first field records an occupation status of the data, the second field indicates a node that occupies the data exclusively when the first field includes an exclusive state, and the node controller determines a second entry in the second table according to the address information of the data and the second field when the first field includes a shared state, where the second entry includes a third field, and the third field indicates nodes that share the data.
