Abstract
An arithmetic logic unit according to an embodiment of the present technology includes: a plurality of input lines; and a multiply-accumulate operation device. Pulse signals corresponding to input values are input to the plurality of input lines. The multiply-accumulate operation device includes a plurality of multiplication units that generates, on the basis of the pulse signals input to each of the plurality of input lines, charges corresponding to multiplication values obtained by multiplying the input values by weight values, and an output unit that outputs a multiply-accumulate signal representing a sum of the multiplication values by accumulating the charges corresponding to the multiplication values generated by each of the plurality of multiplication units. A value of at least one of the input value or the weight value is limited.
