How does DMA controller work? Give an example of DMA data transfer. [5]
Direct Memory Access (DMA) is a process for data transfer between memory and I/O devices, controlled by an external circuit called the DMA controller, without the direct involvement of the CPU. It saves CPU processing time and provides a more efficient way to move data. --- The DMA controller use...
