GENERAL NOTE
Supported System Architectures
This data sheet provides preliminary information for the
ADSP-21mod980N-210 Multiport Internet Gateway
Processor Solution.
The ADSP-21MOD980N-210 Multiport Internet
Gateway Processor supports two system architectures: serial
Telco PCM TDM data stream and parallel Telco PCM data
stream. The two architectures are differentiated by the
method of proving Telco PCM data to the DSP Modem.
GENERAL DESCRIPTION
The ADSP-21MOD980N-210 is a sixteen-channel
solution intended for remote access server and remote
access concentrator applications. It combines a highly integrated DSP processor with downloadable software. All data
pump and controller functions are implemented on a single
1.9-square-inch device. This modem package allows the
highest modem port density while achieving the lowest
power consumption in a software upgradeable platform.
The ADSP-21MOD980N-210 is designed for high-density
systems such as remote access servers, see the functional
block diagram on page 1. Its high performance DSP core,
large on-device SRAM, TDM serial port and 16-bit DMA
port provide efficient control and data communication with
minimal device count. The modem software provides a
number of data modulations, such as V.90, K56 flex™, V.34,
and ISDN with a software upgrade path to future standards
and new applications, such as voice over network. The host
interface allows system access to modem statistics such as
call progress, connect speed and modulation parameters
such as retrain count and symbol rate.
On-device RAM
Serial Telco PCM TDM Data Stream Architecture
The serial Telco PCM TDM data stream architecture,
shown in Figure 1 on page 3, is the most common architecture. In this architecture, the modem pool may have a local
Telco interface that provides a serial TDM data stream of
Telco PCM data to the DSP through the DSP’s Serial Port.
You can connect up to 24/32 DSPs, through the Serial Port,
to a 24-/32-channel serial TDM data stream.
Parallel Telco PCM Data Stream Architecture
The parallel Telco PCM data stream architecture, shown in
Figure 2 on page 3, provides a single bus interface for all
data and control. In this architecture, the modem pool may
have a remote Telco interface that provides a parallel data
stream of Telco PCM data to the DSP through the DSP’s
DMA Port. An arbitrary number of DSPs can be connected,
through the DMA Port, to a Host that provides the parallel
data stream.
Note: The number of parallel DSPs is limited only by the
software loading constraints on the Host.
The ADSP-21MOD980N-210 processor integrates 16 M
bits of on-device memory. The modem datapump and controller software, as well as data storage, are contained in the
on-device RAM. The RAM cells are designed by Analog
Devices. These cells are optimized for high speed digital
signal processing and low power consumption.
Software Interface
You can dynamically configure the
ADSP-21MOD980N-210 with software through the 16-bit
DMA interface.
The DMA Port on the ADSP-21MOD980N-210 contains
an auto-incrementing address generator. The host writes
the starting address of the transfer and then writes the first
word of data.
DMA Interface
The 16-bit internal DMA port (DMA Port) provides transparent, direct access to the on-device RAM of the
ADSP-21MOD980N-210 processor. This high speed
access to on-device memory simplifies control and data
communication and system debug. Use the 16-bit DMA
interface to dynamically configure the
ADSP-21MOD980N-210 with software.
Serial Ports
The ADSP-21MOD980N-210 processor incorporates two
complete synchronous, double-buffered serial ports for
serial communications. The serial ports interface directly to
a time-division multiplexed (TDM) 1544 kbps (T1) or
2048 kbps (E1) serial stream, to an 8K sample/s data stream,
or to an 8-bit companded (64 kb/s) data stream (DS0). The
serial ports operate under modem software control.
2
Analog Devices provides sample C code for the software
inter-face to the ADSP-21MOD980N-210. The software
interface includes the following four areas—download,
control interface, data interface and modem statistics.
Download
After the first write, the DMA address generator automatically increments; the host writes the next data word and the
DMA transfers that word to the next location in
ADSP-21MOD980N-210 memory.
The executable image contains code and data that must be
loaded into program and data memory. Program memory
on the ADSP-21MOD980N-210 is 24 bits wide, therefore
two transfers are used to load each word of program
memory.
The host begins the download by asserting the RESET pin
of the ADSP-21MOD980N-210. The host then transfers
all code and data. All internal memory can be loaded in 5
ms.

Control Interface
Data Interface
The ADSP-21MOD980N-210 is controlled through two
FIFOs in DSP memory. The host sends a control event by
writing to the host-to-modem FIFO. The
ADSP-21MOD980N-210 posts events to the host by
writing into the modem-to-host FIFO.
All data transferred to and from the ADSP 21mod970-110
passes through word FIFOs located in internal memory on
the ADSP-21MOD980N-210. The FIFOs are accessed
through a control structure that contains a pointer to the
start of the FIFO in memory, the length of the FIFO in

16-bit words, a pointer to the next address to be read, and
a pointer to the next address to be written. The transmit and
receive FIFOs are 1024 bytes deep.
Example code providing primitives for accessing the
byte-FIFOs is available from Analog Devices. Figure 3 on
page 4 shows an example of a data FIFO.
