Abstract
Methods and devices are provided for implementing efficient general deconvolution Implementation on hardware accelerator. In one method for implementing a devolution operation to obtain a multi-dimensional output feature map in a pre-defined dimensional count, a multi-dimensional kernel is subsampled into a plurality of non-overlapping multi-dimensional sub-kernels, each in the pre-defined dimensional count, based on a pre-defined common stride parameter, a plurality of multi-dimensional sub-output feature maps in the pre-defined dimensional count is obtained by applying a stride-dependent virtual padded devolution operation between a multi-dimensional input map and each multi-dimensional sub-kernel in the plurality of non-overlapping multi-dimensional sub-kernels, and in response to determining the pre-defined common stride parameter is not greater than two, a pre-defined multi-dimensional interleave-concatenation method is used to interleave-concatenate and reorder the plurality of multi-dimensional sub-output feature maps into the multi-dimensional output feature map.
