Abstract: An audio processing method includes: obtaining relative attitude information between a lens and a plurality of microphones, where the lens is movable relative to at least one of the plurality of microphones; obtaining original audio signals acquired by the plurality of microphones; determining weight information corresponding to the original audio signals based on the relative attitude information; and synthesizing the original audio signals based on the weight information to obtain a target audio signal, where the target audio signal is played with images captured by the lens. The method disclosed in this application resolves a problem that a sound source orientation indicated by recorded audio does not match the images captured by the lens.

Abstract: This application relates to the field of data communication, and in particular, to a packet buffering method, an integrated circuit system, and a storage medium. The method can improve utilization of the on-chip buffer. The packet buffering method may be applied to a network device. The network device includes a first storage medium and a second storage medium. The first storage medium is a local buffer, and the second storage medium is an external buffer. The method may include: receiving a first packet, and identifying a queue number of the first packet, where the queue number indicates a queue for storing the first packet; querying a queue latency based on the queue number; determining a first latency threshold based on usage of the first storage medium; and buffering the first packet in the first storage medium or the second storage medium based on the queue latency and the first latency threshold.

Abstract: A method and apparatus for dequeuing data are disclosed. The method includes: obtaining storage addresses of packets in each queue, and dequeuing, by multiple dequeue processing engines, the packets in each queue in parallel according to the storage addresses of the packets in each queue. Multiple dequeue processing engines dequeue the packets in multiple queues in parallel, and thus the data dequeue efficiency and performance are improved.

Abstract: A system and a method for writing cache data and a system and a method for reading cache data are disclosed. The system for writing the cache data includes: an on-chip memory device, configured to cache received write requests and write data associated with the write requests and sort the write requests; a request judging device, configured to extract the sorted write requests and the write data associated with the write requests according to write time sequence restriction information of an off-chip memory device; and an off-chip memory device controller, configured to write the write data extracted by the request judging device in the off-chip memory device.

Abstract: A method, an apparatus, and a system for processing buffered data are disclosed. The method includes: packing data packets in a same queue; splitting the packed data packet into multiple data cells according to a predetermined cell size; and storing the split data cells in multiple memories. The preceding method, apparatus, and system improve the read and write efficiency of the memories and improve the balance of the read and write bandwidths among multiple memories, thus improving the system performance.
