ADSP-TS101S
The DMA controller also supports 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 regis-
ters for both the X and Y dimensions.
The DMA controller performs the following DMA operations:
• External port block transfers. Four dedicated bidirectional
DMA channels transfer blocks of data between the DSP’s
internal memory and any external memory or memory-
mapped peripheral on the external bus. These transfers
support master mode and handshake mode protocols.
• Link port transfers. Eight dedicated DMA channels (four
transmit and four receive) transfer quad word data only
between link ports and between a link port and internal or
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.
