DMA Controller
The ADSP-2106x’s on-chip DMA controller allows zero-over-
head data transfers without processor intervention. The DMA
controller operates independently and invisibly to the processor
core, allowing DMA operations to occur while the core is simul-
taneously executing its program instructions.
DMA transfers can occur between the ADSP-2106x’s internal
memory and external memory, external peripherals, or a host
processor. DMA transfers can also occur between the ADSP-
2106x’s internal memory and its serial ports or link ports. DMA
transfers between external memory and external peripheral
devices are another option. External bus packing to 16-,
32-, or 48-bit words is performed during DMA transfers.
Ten channels of DMA are available on the ADSP-2106x—two
via the link ports, four via the serial ports, and four via the
processor’s external port (for either host processor, other
ADSP-2106xs, memory, or I/O transfers). Four additional link
port DMA channels are shared with Serial Port 1 and the exter-
nal port. Programs can be downloaded to the ADSP-2106x
using DMA transfers. Asynchronous off-chip peripherals can

control two DMA channels using DMA request/grant lines
(DMAR1–2, DMAG1–2). Other DMA features include inter-
rupt generation upon completion of DMA transfers and DMA
chaining for automatic linked DMA transfers.
Multiprocessing
The ADSP-2106x offers powerful features tailored to multipro-
cessor DSP systems. The unified address space (see
allows direct interprocessor accesses of each ADSP-2106x’s
internal memory. Distributed bus arbitration logic is included
on-chip for simple, glueless connection of systems containing
up to six ADSP-2106xs and a host processor. Master processor
changeover incurs only one cycle of overhead. Bus arbitration is
selectable as either fixed or rotating priority. Bus lock allows
indivisible read-modify-write sequences for semaphores. A vec-
tor interrupt is provided for interprocessor commands. Maxi-
mum throughput for interprocessor data transfer is
240M bytes/s over the link ports or external port. Broadcast
writes allow simultaneous transmission of data to all
ADSP-2106xs and can be used to implement reflective
semaphores.
