Classification: CPC G | IPC G

Claim 35:
36. A convolutional neural network (CNN) processing apparatus, comprising:
a processor configured to:
selecting a survival network in a precision convolutional network based on an attention result of a forward pass operation of the CNN subsequent to perform a high-speed convolution operation between high-order bits of an input and high-order bits of a kernel while ignoring low-order bits of the input and low-order bits of the kernel;
perform a precision convolution operation based on at least the low-order bits of the input and the low-order bits of the kernel; and
generate an output by combining a result of performing the high-speed convolution operation and a result of performing the precision convolution operation,
wherein the kernel used in performing the high-speed convolution operation is also used in performing the precision convolution operation, and
wherein a convolutional layer in which the high-speed convolution operation is performed is the same as a convolutional layer in which the precision convolution operation is performed.
