INTRODUCTION
The ADSP-21mod870-110 is a complete single chip. All data-
pump and controller functions are implemented on a single
0.4 square-inch chip. This modem package allows the highest
modem port density, while achieving the lowest power con-
sumption in a software upgradable platform.
The ADSP-21mod870-110 is designed for high density systems
such as remote access servers (see Figure 1). Its high perfor-
mance DSP core, large on-chip SRAM, TDM serials port and
16-bit DMA port provide efficient control and data communi-
cation with minimal chip count. The modem software provides
a number of data modulations, such as V.34, 56K bps PCM,
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-CHIP SRAM
The ADSP-21mod870-110 processor integrates 160K bytes of
on-chip memory. The modem datapump and controller soft-
ware, as well as data storage, are contained in the on-chip SRAM.
The SRAM cells are designed by Analog Devices. These cells
are optimized for high speed digital signal processing and low
power consumption. You can dynamically configure the ADSP-
21mod870 with software through the 16-bit DMA interface.
DMA INTERFACE
The 16-bit internal DMA port (IDMA port) provides transpar-
ent, direct access to the on-chip RAM of the ADSP-21mod870
processor. This high speed access to on-chip memory simplifies
control and data communication and system debug. Use the
16-bit DMA interface to dynamically configure the ADSP-
21mod870 with software.
