DMA Controller

Definition: DMA or Direct Memory Access Controller is an external device that controls the transfer of data between I/O device and memory without the involvement of the processor. It holds the ability to directly access the main memory for read or write operation. DMA controller was designed by Intel, to have the fastest data transfer …
