Introduction

The DSP1648C, host-accelerated modem chip is an

exciting new upgrade to Agere Systems Inc. line of

host-based controller modems. The DSP1648C

upgrades the technologies found in the DSP1648

V.90 modem solution to the new ITU-T

recommendations V.92 and V.44 communication

industry standards. V.92 and V.44 have four innova-

tive features, designed to improve modem perfor-

mance in the internet environment. The new features

are as follows:

The DSP1648C has an integrated PCI interface,

which eliminates the 16550 UART bottleneck found

in traditional hardware modems. The PCI interface

supports both slave and master operations while pro-

viding greater access to host PC system resources.

Host-based controller modems have the benefit of

using powerful CPUs and accessing their plentiful

RAM and disk space. Modem firmware can therefore

be updated in the field since the code simply resides

on the disk.

With this feature set, designers can create full-fea-

tured modem solutions which are characterized by

low-cost, low power consumption, and high-perfor-

mance.
