Telogy Software for IP Phone
Applications
Telogy Software provides an
efficient framework for real-time
voice processing that has been
pre-integrated and rigorously
tested. The complete DSP solution
feature set includes: PCM reception,
tone generation, acoustic echo
cancellation, voice activity detection,
voice playout, and a variety of voice
compression options. The solutions
are provided in several packages to
allow customization for a full range
of phone products.
The TNETV1050 also supports
TI’s VLYNQ™ interface; a low cost,
low pin count and low complexity
chip-to-chip serial interface. VLYNQ
makes it easy to add off-chip co-
processors and peripheral capability
to the phone. VLYNQ enables the
customer to bring in value-added
features such as video/multimedia,
wireless connectivity, security,
speech recognition and more.
