Detailed Description

AffineDmaStartOp starts a non-blocking DMA operation that transfers data from a source memref to a destination memref.

The source and destination memref need not be of the same dimensionality, but need to have the same elemental type. The operands include the source and destination memref's each followed by its indices, size of the data transfer in terms of the number of elements (of the elemental type of the memref), a tag memref with its indices, and optionally at the end, a stride and a number_of_elements_per_stride arguments. The tag location is used by an AffineDmaWaitOp to check for completion. The indices of the source memref, destination memref, and the tag memref have the same restrictions as any affine.load/store. In particular, index for each memref dimension must be an affine expression of loop induction variables and symbols. The optional stride arguments should be of 'index' type, and specify a stride for the slower memory space (memory space with a lower memory space id), transferring chunks of number_of_elements_per_stride every stride until num_elements are transferred. Either both or no stride arguments should be specified. The value of 'num_elements' must be a multiple of 'number_of_elements_per_stride'. If the source and destination locations overlap the behavior of this operation is not defined.
