WebJan 13, 2024 · Some caching hardware "snoops" the memory bus, effectively listening for memory access that would hit a cache line in the cache, and then updates the cache automatically. This saves the CPU from having master a separate transaction to get the DMA'd data from RAM into the cache. Additionally, some buses support a priority system … WebWhat is Remote Direct Memory Access (RDMA)? Remote Direct Memory Access is a technology that enables two networked computers to exchange data in main memory without relying on the processor, cache or operating system of either computer. WebDirect memory access (DMA) is a means of having a peripheral device control a processor’s memory bus directly. DMA permits the peripheral, such as a UART, to transfer data directly to or from memory without having each byte (or word) handled by the processor. cuba water delivery
