Abstract: A neural network apparatus performs multiply-accumulate (MAC) operations with respect to fractions of weights and input activations in a block floating-point format by using an analog crossbar array, performs addition operations with respect to shared exponents of weights and input activations in a block floating-point format by using a digital computing circuit, and outputs a partial sum of floating-point output activations by combining the result of the MAC operations and the result of the addition operations.
