Abstract: An intelligence processing unit (IPU) includes a memory, a grid processing circuit, and a convolution computation circuit. The memory is configured to store a part of a first input data of a deformable convolution operation, a part of a bias of the deformable convolution operation, a part of a weight of the deformable convolution operation, and a part of a grid, where the grid is transformed from an offset of the deformable convolution operation. The grid processing circuit is configured to perform a grid-sample operation to generate a second input data based on the first input data and the grid. The convolution computation circuit is configured to perform a convolution operation on the second input data, the weight, and the bias to generate an output data. The output data is substantially equal to the result of the deformable convolution operation.

Abstract: A convolution operation device includes a multiply-accumulate (MAC) circuit and a post-processing circuit. The MAC circuit performs a convolution operation according to first feature data and a weight coefficient to generate initial operation data and generates a completion signal. The post-processing circuit obtains a first shift value from a memory according to the completion signal, performs a bit shift on the initial operation data according to the first shift value to generate shifted operation data, and performs a first clipping operation on the shifted operation data according to a predetermined value range to generate first operation data, wherein the number of bits of the first operation data is less than the number of bits of the initial operation data.
