Two-Dimensional DMA

The DMA is able to address and transfer two-dimensional memory arrays,
where X and Y array dimensions are defined in transmitter and receiver
registers.
TCB
• Receiver array dimensions can differ from those of the transmitter,
as long as the total number of words in source and destination are
equal.
• A two-dimensional memory array can be moved to a one-dimen-
sional array and vice versa, as long as the total number of words in
source and destination are equal.
• A two-dimensional block in memory can be transmitted via links,
or a block received through links or from AutoDMA can be placed
in memory as a two-dimensional array.
