However, sometimes you can overload that brain and CPU designers are always trying to improve both speed and throughput using a variety of techniques. One of those methods is DMA or direct memory ...

Instead of PIO taking up a few percent of the CPU’s cycles, a big transfer could take up most cycles, making the system grind to a halt until the transfer completed. DMA (Direct Memory Access ...

Direct Memory Access (DMA) is a technique for transferring blocks of data between system memory and peripherals without a processor (e.g., system CPU) having to be involved in each transfer. DMA not ...

The AXI CDMA provides high-bandwidth Direct Memory Access (DMA) between a memory-mapped source address and ... feature can be used to offload control and sequencing tasks from the system CPU.
