ADSP-21161N
JTAG emulators provides emulation at full processor speed,
allowing inspection and modification of memory, registers, and
processor stacks. The processor’s JTAG interface ensures that
the emulator will not affect target system loading or timing.

Tools product line of JTAG emulator operation, see the appro-
priate Emulator Hardware User’s Guide. For detailed infor-
mation on the interfacing of Analog Devices JTAG emulators
with Analog Devices DSP products with JTAG emulation ports,
please refer to Engineer to Engineer Note EE-68: Analog Devices
JTAG Emulation Technical Reference. Both of these documents
can be found on the Analog Devices website.
DMA Controller
The ADSP-21161N’s on-chip DMA controller enables zero-
overhead 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 simultaneously executing its program instructions. DMA
transfers can occur between the ADSP-21161N’s internal mem-
ory and external memory, external peripherals, or a host
processor. DMA transfers can also occur between the ADSP-
21161N’s internal memory and its serial ports, link ports, or the
SPI-compatible (Serial Peripheral Interface) port. External bus
packing and unpacking of 32-, 48-, or 64-bit words in internal
memory is performed during DMA transfers from either 8-,
16-, or 32-bit wide external memory. Fourteen channels of
DMA are available on the ADSP-21161N—two are shared
between the SPI interface and the link ports, eight via the serial
ports, and four via the processor’s external port (for host pro-
cessor, other ADSP-21161Ns, memory, or I/O transfers).
Programs can be downloaded to the ADSP-21161N using DMA
transfers. Asynchronous off-chip peripherals can control two
DMA channels using DMA Request/Grant lines (DMAR2–1,
DMAG2–1). Other DMA features include interrupt generation
upon completion of DMA transfers, and DMA chaining for
automatic linked DMA transfers.
