OPERATION CIRCUIT, OPERATION METHOD, AND PROGRAM - A simplified explanation of the abstract

This abstract first appeared for US patent application 18256005 titled 'OPERATION CIRCUIT, OPERATION METHOD, AND PROGRAM

Simplified Explanation

The present invention describes an operation circuit for performing a convolution operation of input feature map information and coefficient information supplied as multiple channels.

• Operation circuit includes at least two channels of an output feature map and three sub-operation circuits.
• Sub-operation circuits execute the convolution operation of coefficient information and input feature map information.
• If a specific channel of the output feature map is a zero matrix, a sub-operation circuit performs the convolution operation of the zero matrix with the next input feature map information.
• Result of the convolution operation is output for each channel of the output feature map.

Original Abstract Submitted

One aspect of the present invention is an operation circuit for performing a convolution operation of input feature map information supplied as a plurality of channels and coefficient information supplied as a plurality of channels, the operation circuit including a set including at least two channels of an output feature map based on output channels and at least three sub-operation circuits, wherein at least two sub-operation circuits are allocated for each set, the sub-operation circuits included in the set execute processing of a convolution operation of the coefficient information and the input feature map information included in the set, when a specific channel of the output feature map is a zero matrix, a sub-operation circuit that performs a convolution operation of the zero matrix executes processing of a convolution operation of the coefficient information and the input feature map information to be supplied next from a channel of the output feature map and a channel of the input feature map included in the set, and a result of the convolution operation is output for each channel of the output feature map.
