Title:
演算処理装置及び演算処理方法
Document Type and Number:
Japanese Patent JP7308674
Kind Code:
B2
Abstract:
An apparatus for calculating feature planes by hierarchically performing filter operation processing for input image data, comprises an operation unit configured to perform a convolution operation, a holding unit including memories configured to store image data and an operation result of the operation unit, a unit configured to receive the operation result, and write, out of the operation result, data of successive lines of the same feature plane in different memories of the memories and write data at the same coordinates of feature planes in the same layer in different memories of the memories, and a unit configured to read out the data of the successive lines from the different memories, read out the data at the same coordinates of the different feature planes in the same layer, and transmit the data to the operation unit.
