Claim 8:
9. A neural network apparatus comprising:
a memory configured to store data of weights and input activations of a neural network; and
one or more processors configured to:
performing a preprocessing to encode the weights of filters of the neural network using an inverted two's complement fixed-point format;
performing a sum-of-products operation with respect to the input activations of the neural network and the encoded weights of a current filter in a bit-serial scheme; and
when it is determined that a sign of an intermediate resultant value of the sum-of-products operation for the current filter is negative, performing a sum-of-products operation with respect to the input activations and the encoded weights of a next filter in the bit-serial scheme by skipping the sum-of-products operation for the current filter.
