DMA data transfer

The position of the DMA controller between the other components in a computer system. The CPU communicates with the DMA by the  address and data buses as with any interface unit.  The DMA has its own address,  which activates the DS and RS lines.  The CPU initializes the DMA by the data  bus.  Once the DMA receives the start control command, it can start the transfer among the peripheral device and the memory.
