external memory. These transfers only use handshake
mode protocol. DMA priority rotates between the four
receive channels.

• AutoDMA transfers. Two dedicated unidirectional DMA

channels transfer data received from an external bus master
to internal memory or to link port I/O. These transfers only
use slave mode protocol, and an external bus master must
initiate the transfer.

The DMA controller provides these additional features:

• Flyby transfers. Flyby operations only occur through the

external port (DMA Channel 0) and do not involve the
DSP’s core. The DMA controller acts as a conduit to trans-
fer data from an I/O device to external SDRAM memory.

During a transaction, the DSP relinquishes the external
data bus; outputs addresses and memory selects
(MSSD3–0); outputs the IORD, IOWR, IOEN, and
RD/WR strobes; and responds to ACK.

• DMA chaining. DMA chaining operations enable applica-

tions to automatically link one DMA transfer sequence to
another for continuous transmission. The sequences can
occur over different DMA channels and have different
transmission attributes.

• Two-dimensional transfers. The DMA controller can

access and transfer two-dimensional memory arrays on any
DMA transmit or receive channel. These transfers are
implemented with index, count, and modify registers for
both the X and Y dimensions.
