Abstract: A multiple chip multiprocessor cache coherence operation method and a multiple chip multiprocessor are disclosed. The method includes: receiving a write request for a first data block; finding, in an on-chip directory of the first processor chip, an on-chip directory entry corresponding to the first data block based on an identifier of the first data block, determining, from the found on-chip directory entry, a core identifier of a processor core storing the first data block, sending, to the processor core corresponding to the core identifier, an instruction message for deleting the first data block, skipping sending an inter-chip directory query request for the first data block, and instructing the first processor core to write the to-be-written data into a private cache of the first processor core.

Abstract: The present disclosure discloses a method for accessing a data visitor directory in a multi-core system, a directory cache device, a multi-core system, and a directory storage unit. The method includes: receiving a first access request sent by a first processor core, where the first access request is used to access an entry, corresponding to a first data block, in a directory; determining, according to the first access request, that a single-pointer entry array has a first single-pointer entry corresponding to the first data block; when determining, according to the first single-pointer entry, that a sharing entry array has a first sharing entry associated with the first single-pointer entry, determining multiple visitors of the first data block according to the first sharing entry. According to embodiments of the present disclosure, storage resources occupied by a directory can be reduced.

Abstract: This application relates to a ranging positioning scenario in the field of wireless communication sensing. Example methods, devices, and non-transitory machine-readable storage medium relate to ranging in ultrawideband (UWB) applied in a wireless local area network, which may support the 802.15.4z standard. One example method includes: extracting, by two communication devices (for example, a first device and a second device) key sequences based on wireless channel information (for example, channel state information) between respective narrowband communication modules (for example, Wi-Fi, Bluetooth, or Zigbee). The example method includes providing the key sequences to respective UWB modules, and performing ranging based on the key sequences.
