Neural electronic circuit

A neural electronic circuit, comprising:

• a storage unit that stores a logarithmic weighting coefficient, in which a value obtained by logarithmizing a weighting coefficient corresponding to input data that is input is expressed in multiple bits, and outputs the logarithmic weighting coefficient bit by bit;
• a first electronic circuit unit that outputs a multiplication result of the input data and the weighting coefficient;
• and
• a second electronic circuit unit that realizes addition and application functions for adding up the multiplication results from the first electronic circuit units, applying an activation function to the addition result, and outputting output data,
• wherein the first electronic circuit unit receives logarithmic input data, in which a value obtained by logarithmizing the input data is expressed in multiple bits, bit by bit, calculates a logarithmic addition by adding up the logarithmic input data and the logarithmic weighting coefficient output from the storage unit, and calculates the multiplication result by linearizing the logarithmic addition result, and
• the second electronic circuit unit outputs the output data that is logarithmized.
