Electronic circuit, in particular capable of implementing a neural network, and neural system

A circuit, comprising:

• a series of neuro-blocks configured to implement a neural network, said neuro-blocks (i) each comprising a plurality of neurons and (ii) being grouped together in branches, each of the branches comprising a group of neuro-blocks and a broadcasting bus, the neuro-blocks being connected to said broadcasting buses;
• a routing unit connected to the broadcasting buses of said branches and configured to route data to said branches;
• and
• a transformation module connected to the routing unit via an internal bus and configured to be connected, at an input of said circuit, to an external bus, said module carrying out a transformation of a format of data inputted by said external bus, a first message of N input words with x bits coded in parallel being transformed into a second message of N words with x bits coded in series, the N words of the second message being parallelized over the internal bus at an output of said module, one wire of the internal bus being dedicated to each of the N transformed words, one bit of the each word being sequentially broadcast over the broadcasting buses of the branches via the routing unit at a time such that all processing operations of the series of the neuro-blocks are carried out according to a serial communications protocol,
• wherein an inverse transformation is performed by the transformation module such that a third message of N words with the x bits coded in series is transformed into a fourth message of N output words with the x bits coded in parallel.
