host processor, other ADSP-21160Ms, memory or I/O
transfers). Programs can be downloaded to the
ADSP-21160M 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, two-dimensional DMA, and
DMA chaining for automatic linked DMA transfers.
Multiprocessing
The ADSP-21160M offers powerful features tailored to
multiprocessing DSP systems as shown in
Figure 4
. The
external port and link ports provide integrated glueless mul-
tiprocessing support.
The external port supports a unified address space (see
Figure 2
) that allows direct interprocessor accesses of each
ADSP-21160M
’
s internal memory. Distributed bus arbitra-
tion logic is included on-chip for simple, glueless connection
of systems containing up to six ADSP-21160Ms 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-mod-
ify-write sequences for semaphores. A vector interrupt is
provided for interprocessor commands. Maximum
throughput for interprocessor data transfer is 320M bytes/s
over the external port. Broadcast writes allow simultaneous
transmission of data to all ADSP-21160Ms and can be used
to implement reflective semaphores.
Six link ports provide for a second method of multiprocess-
ing communications. Each link port can support
communications to another ADSP-21160M. Using the
links, a large multiprocessor system can be constructed in a
2D or 3D fashion. Systems can use the link ports and cluster
multiprocessing concurrently or independently.
Link Ports
The ADSP-21160M features six 8-bit link ports that
provide additional I/O capabilities. With the capability of
running at 80 MHz rates, each link port can support 80M
bytes/s. Link port I/O is especially useful for point-to-point
interprocessor communication in multiprocessing systems.
The link ports can operate independently and simulta-
neously. Link port data is packed into 48- or 32-bit words,
and can be directly read by the core processor or
DMA-transferred to on-chip memory. Each link port has its
own double-buffered input and output registers.
Clock/acknowledge handshaking controls link port trans-
fers. Transfers are programmable as either transmit
or receive. For data throughput information, see link port
timing details in
Table 18 on page 34
.
Serial Ports
The ADSP-21160M 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 up to half the clock rate of the core, providing
each with a maximum data rate of 40M bit/s. Independent
