| * Parameter set for "convolution" type GEMM. |
| * |
| * For a "convolution" GEMM, the GEMM parameters (M, K) are specified as if |
| * an im2row had been performed on the input tensor to generate the operand |
| * matrix, but instead this structure describes the convolution parameters |
| * such that this can be done on the fly. |
| * |
| * The parameters describe the convolution details - the notional shape of |
| * the input and output tensors, whether padding is to be applied, the size |
| * of the kernel and a constant value to be used for padding (needed for |
| * quantized tensors). |
| * |
| * The second part describes the layout of the input tensor in memory, which |
| * is assumed to be in NHWC format. This consists of a base pointer and |
| * strides for columns, rows and batches. 'multis' are not supported for |
| * convolution type GEMMs. |
