Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 34:
35. A convolutional neural network (CNN) processing apparatus comprising:
a processor configured to:
generate an approximate output by performing a high-speed convolution operation between a subset of bits for each of plural input elements of an input and a kernel;
select a survival network in a convolutional layer based on the approximate output;
perform a precision convolution operation between another subset of bits for each of the plural input elements of the input and the kernel using the survival network; 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
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.
