Classification: CPC G | IPC G

Claim 6:
7. The neural network circuit device according to claim 1,
wherein the convolution operation circuit includes: a first storage part that stores therein a nonzero weight and a relative address of an input value X to which convolution is applied; and a second storage part that stores therein an address of the input value Xi, and
wherein the convolution operation circuit is configured to, in performing an operation in which a zero weight is skipped,
retrieve a nonzero weight and a relative address corresponding thereto, from the first storage part,
reference the second storage part and retrieve therefrom a subsequent input value X to which convolution is applied, using the retrieved relative address and a current address, and
perform a convolution operation based on the input value Xi retrieved from the second storage part and a nonzero weight corresponding thereto.
