Six channels of DMA are available on the ADSP-21061—four
via the serial ports, and two via the processor’s external port (for
either host processor, other ADSP-21061s, memory or I/O
transfers). Programs can be downloaded to the ADSP-21061
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 interrupt
generation upon completion of DMA transfers and DMA
chaining for automatic linked DMA transfers.
Serial Ports
The ADSP-21061 features two synchronous serial ports that
provide an inexpensive interface to a wide variety of digital and
mixed-signal peripheral devices. The serial ports can operate at
the full clock rate of the processor, providing each with a maxi-
mum data rate of up to 50 Mbps. Independent transmit and
receive functions provide greater flexibility for serial communi-
cations. Serial port data can be automatically transferred to and
from on-chip memory via DMA. Each of the serial ports offers
TDM multichannel mode.
The serial ports can operate with little-endian or big-endian
transmission formats, with word lengths selectable from 3 bits
to 32 bits. They offer selectable synchronization and transmit
modes as well as optional μ-law or A-law companding. Serial
port clocks and frame syncs can be internally or externally gen-
erated. The serial ports also include keyword and key mask
features to enhance interprocessor communication.
Multiprocessing
The ADSP-21061 offers powerful features tailored to multipro-
cessor DSP systems. The unified address space (see Figure 4)
allows direct interprocessor accesses of each ADSP-21061’s
internal memory. Distributed bus arbitration logic is included
on-chip for simple, glueless connection of systems containing
up to six ADSP-21061s 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 500 Mbps
over the external port. Broadcast writes allow simultaneous
transmission of data to all ADSP-21061s and can be used to
implement reflective semaphores.
