![]() ![]() ![]() During the DMA process, CPU initiates the data transfers, and the remaining process of data transfer is handled by the DMA. The DMA directly accesses the main memory and bypass the CPU all together, to reduce the impact of data transfers on performance. With large transfers, the CPU gets significant drops in performance. The basic process of the data transfer goes through the CPU and then transferred to the appropriate destination. The traditional data transfer between a host system’s main memory and an external device is controlled by the central processing unit (CPU) and is used by the programmed input/output or interrupt-driven I/O.
