Abstract
Latency reduction for direct memory access operations involving address translation is disclosed. Example methods disclosed herein to perform direct memory access (DMA) operations include initializing a ring of descriptors, the descriptors to index respective buffers for storing, in a first memory, data to be transmitted. Such example methods also include causing prefetching of a first address translation associated with a second descriptor in the ring of descriptors to be performed after a first DMA operation is performed to retrieve, for transmission, first data from a first buffer indexed by a first descriptor in the ring of descriptors and before second data is determined to be ready for transmission, the first address translation being associated with a second DMA operation for retrieving the second data from the first memory.
