Abstract: Embodiments of this application provide a communication method and apparatus. The apparatus includes a receiving module and a sending module. When the receiving module receives a user equipment UE capability query message sent by a network device, the sending module sends a first UE capability message (including a first UE capability specification) to the network device, and when determining that a network exception occurs, sends a second UE capability message (including a second UE capability specification that is lower than the first UE capability specification) to the network device. This helps implement mutual compatibility between the terminal device and the network device, thereby ensuring that a communication link can be quickly established between the terminal device and the network device. In this way, a user can normally use the terminal device, and the terminal device can keep using a high-standard network as much as possible, thereby improving user experience.

Abstract: This application provides a communication method and a terminal apparatus. The communication method includes: A terminal apparatus receives a trigger message, where the trigger message includes a notification information identifier. When the terminal apparatus does not store notification information corresponding to the notification information identifier, the terminal apparatus ignores the trigger message. In this method, when receiving a useless trigger message, the terminal apparatus does not perform processing, thereby reducing power consumption.

Abstract: A spiking neural network circuit implemented in a chip includes a plurality of decompression modules and a calculation module. The plurality of decompression modules are configured to obtain a plurality of weight values in a compressed weight matrix and identifiers of a plurality of corresponding output neurons based on information about a plurality of input neurons. Each of the plurality of decompression modules is configured to obtain weight values with a same row number in the compressed weight matrix and identifiers of a plurality of output neurons corresponding to the weight values with the same row number. Each row of the compressed weight matrix has a same quantity of non-zero weight values. Each row of weight values corresponds to one input neuron. The calculation module then determines corresponding membrane voltages of the plurality of output neurons based on the plurality of weight values.

Abstract: This application discloses a data prefetching method, including: receiving, by a home node, a write request sent by a first cache node after the first cache node processes received data; performing, by the home node, an action of determining whether the second cache node needs to perform a data prefetching operation on the to-be-written data; and when determining that the second cache node needs to perform a data prefetching operation on the to-be-written data, sending, by the home node, the to-be-written data to the second cache node. Embodiments of this application help improve accuracy and certainty of a data prefetching time point, and reduce a data prefetching delay.
