摘要： Examples are disclosed for distributing Ethernet data processing across multiple processing cores. In one example, a computing system includes a main host processor including multiple processing cores and a shared on-chip memory accessible by each of the multiple processing cores, and an Ethernet hardware subsystem communicatively coupled to the main host processor via a direct memory access (DMA) subsystem, the DMA subsystem configured to route data from the Ethernet hardware subsystem to one or more of the multiple processing cores.

摘要： Embodiments are disclosed for a device for determining which packets of an audio/video stream include a valid presentation time. In some embodiments, a device comprises a communication interface communicatively connectable to another device and configured to transmit data, a processor, and a storage device that stores instructions executable by the processor to designate a sample of an audio/video stream as including a valid presentation time responsive to a sum of a number of data blocks that have been sampled since a last valid presentation time stamped data block and a number of data blocks in the sample being greater than or equal to a threshold value.

摘要： Embodiments are disclosed for a device for determining a number of sample blocks to include in a packet. In some embodiments, a device comprises a communication interface communicatively connectable to another device and configured to transmit data, a processor, and a storage device that stores instructions executable by the processor to determine a total sample size of samples stored in a transmission buffer. The instructions are further executable to calculate a bandwidth credit based on a reserved bandwidth and an elapsed time since a last sent packet, determine a number of sample blocks to include in a packet based on the total sample size and the bandwidth credit, and generate a packet including the determined number of sample blocks.
