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 received data in a first memory. 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 store first received data in a first buffer indexed by a first descriptor in the ring of descriptors and before second received data to be stored in the first memory is received, the first address translation being associated with a second DMA operation for storing the second received data in the first memory.
