Abstract

A multiplier for calculating a multiplication of a first fixed point number and a second fixed point number comprises a converter and a restoration circuit. The converter is configured to convert the first fixed point number to a sign, a mantissa, and an exponent. At least one of a bit width of the sign, a bit width of the mantissa, and a bit width of the exponent is dynamically configured based on a position of a layer associated with the first fixed point number in a neural network, a position of a pixel in an input feature map associated with the first fixed point number, and/or a channel associated with the first fixed point number. The restoration circuit is configured to calculate the multiplication based on the sign, the mantissa, the exponent, and the second fixed point number.
