<p><P>PROBLEM TO BE SOLVED: To provide a convolution operation circuit, a hierarchical convolution circuit and an object recognition device for executing a convolution operation at a high speed by simple configurations. <P>SOLUTION: A control part 101, storage parts 102 to 103, shift registers 104 to 106, a plurality of operation units 107, a plurality of cumulative adders 108 and a non-linear conversion processing part 109 are installed in a CNN processing part. A CNN processing part functions as a hierarchical convolution operation circuit for performing parallel processing in a column direction. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
