Distributed neural network processing

A data processing system comprising a first data processing device to execute part of a neural network by performing operations comprising:

• generating a data stream via a data stream source associated with the first data processing device;
• executing, by at least one first neural network processor of the first data processing device, a first sub-network of the neural network to process the data stream and to provide a processed data stream;
• and
• transmitting, by the first data processing device, the processed data stream to a second data processing device via a data communication channel, wherein a second sub-network of the neural network is executed by at least one second neural network processor of the second data processing device to further process the processed data stream and to provide a further processed data stream.
