When used correctly, DMA can dramatically reduce CPU overhead, improve system responsiveness, and enable designs that would otherwise be impossible with polling or interrupt-driven approaches. This guide explains how DMA controllers work, when they provide real benefits, how to configure them properly, and the common mistakes that lead to data corruption and system crashes.
