Direct Memory Access (DMA) is a appliure in embedded systems that alls to transfer data directly to or from memory with out encluving thee central procesing unit (CPU). This capability enables high- speed data transfer, reducing CPU scaud and improving overall systemem effectency.
Understanding DMA in Embedded Systems
DMA controllers managere data transfers between periferals and memory, freeing thee CPU to perforum their tasks. This is especially useful in applications requiring rapid data movement, such as audio procesing, data logging, and communication interfaces.

Provedení DMA in Embedded Applications
Implementation impeves configuing the DMA controller with source and destination addresses, transfer size, and transfer mode. Many microcontrollers providee registers and APIs to compatiate this setup. Proper configuration ensures reliable and condiment data movement.
