Direct Memory Acces (DMA) i s a feature in embedded systems thathad allows hardware regulents to transfer data directly o or from memory with out contravig the CPU. Tiss capability can excentantly improvie system performance and efactivity by reducing CPU load and and enabling fastir data transfers.

Understanding DMA in Embedded Systems

DMA controllers manage data transfers between een periferals and d memory, freeing the CPU to perform othr tasks. Tiss i esspecialy useful in applications requiring high- speed data processing, such a audio, video, and communication systems.
