During DMA transfers DMA manager takes control of the
transfer of data from specified source address to
destination address. 1D-1D or 1D-2D or 2D-1D or even 2D-2D
transfers are usually possible. During this time processor
is free to perform other operations - which are independent
of the impending transfer being performed.
