memorytransfer
Memory transfer, in the context of computer systems, refers to the movement of data between memory components or between memory and input/output devices. It encompasses data movements initiated by the processor as well as those performed autonomously by hardware such as direct memory access (DMA) controllers or the memory subsystem. The term is often contrasted with computation, which uses memory data as input to perform operations.
Two primary metrics describe memory transfers: bandwidth and latency. Bandwidth measures the rate at which data
Common mechanisms include CPU-initiated transfers, using load and store instructions that move data through caches to
Software performance often depends on memory transfer efficiency. Contiguous, aligned data and streaming access patterns improve
In multi-core and multi-processor systems, memory transfer performance is also impacted by cache coherence, memory locking,
