Method and device for determining the overall memory size of a global memory area allocated to data from a neural network taking into account its topology

摘要

Method for determining the overall memory size of a global memory area (ZG) to be allocated in a memory (MV) intended to store input data and output data of each layer of a neural network (RN) , the method comprising for each current layer of the network subsequent to the first layer, a determination of a pair of elementary memory areas (ZA1, ZA2) from each previous elementary memory area associated with the preceding layer, the two elementary memory areas (ZA1, ZA2) of said pair having respectively two elementary memory sizes and both being intended to store input data and output data of said layer, the output data being stored in respectively two different locations, the size global memory corresponding to the smallest elementary memory size at the output of the last layer.
