Figure 25-2. DMAC Transfer Hierarchy for Non-Memory Peripheral
Figure 25-3. DMAC Transfer Hierarchy for Memory
Block: A block of DMAC data. The amount of data (block length) is determined by the flow con-
troller. For transfers between the DMAC and memory, a block is broken directly into a sequence
of AMBA bursts and AMBA single transfers. For transfers between the DMAC and a non-mem-
ory peripheral, a block is broken into a sequence of DMAC transactions (single and bursts).
These are in turn broken into a sequence of AMBA transfers.
Transaction: A basic unit of a DMAC transfer as determined by either the hardware or software
handshaking interface. A transaction is only relevant for transfers between the DMAC and a
source or destination peripheral if the source or destination peripheral is a non-memory device.
There are two types of transactions: single and burst.
– Single transaction: The length of a single transaction is always 1 and is converted
– Burst transaction: The length of a burst transaction is programmed into the DMAC.

to a single AMBA transfer.
The burst transaction is converted into a sequence of AMBA bursts and AMBA
single transfers. DMAC executes each AMBA burst transfer by performing
incremental bursts that are no longer than the maximum AMBA burst size set. The
