Electronic calculator for the implementation of an artificial neural network, with calculation blocks of several types

An electronic calculator configured to implement an artificial neural network having multiple processing layers,

• the calculator comprising a plurality of electronic calculation blocks, each configured to implement one or more respective processing layers,
• wherein the calculation blocks are of at least two different types from the group of types consisting of:
• a first type with fixed topology, fixed operation, and fixed parameters,
• a second type with fixed topology, fixed operation, and modifiable parameters, and
• a third type with modifiable topology, modifiable operation, and modifiable parameters,
• for the processing layer(s) implemented by the respective calculation block, the topology being a connection topology for each artificial neuron of the processing layer(s), the operation being a type of processing to be performed for each artificial neuron of the processing layer(s) and the parameters including values able to be determined via training of the neural network.
