US Patent 11093168 Processing of neural networks on electronic devices

A data processing system comprising a processor operable to execute a neural network, and associated methods for operating data processing systems. The data processing system comprises the processor and a memory for storing data relating to neural network processing being performed by the processor. The data processor is operable to write to the memory and to read from the memory blocks of data corresponding to regions of a data array generated by the neural network. The writing (or reading) is performed based on a signature comparison between the block of data that is to be written to (or read from) memory and a block of data that is already stored in memory.
