The 3DSP family of synthesizable DSP cores are built on the high performance, low power, SuperSIMD™ (Super-scalar, Single Instruction Multiple Data) proprietary architecture.

3DSP has created a suite of application software designed for VoP technology. These applications include a comprehensive set of speech coders, echo cancellation, and other telephony functions. The VoP software suite is optimized for 3DSP cores.

Applications for VoP
Trunk Media
Gateway
Access Media
Gateway
Convergence
Switch
VoDSL Gateway
Packet Cable
Gateway
Wireless PBX/Base
Station
Residential
Gateway
SOHO Router/PBX
Integrated Access
Device (IAD)

Optimized Programs
G.165/168 - echo
canceller
G.711
G.722
G.723.1+A
G.726
G.729A+B
G.729E+G
GSM EFR
General Purpose
Tone Generator /
Detector
DTMF Detector
MFR1&2 Detector
CLASS Features
(eg. Caller ID and
Call Waiting)
SPEEDi™ RTOS
(Third-party
licenses may be
required.)



A single core is well suited for IAD applications. Scalable multi-channel solutions can be realized by integrating multiple cores along with other interfaces (such as compact PCI, TDM, T1, Utopia, etc). These components are interconnected on the die with the DSP-Shuttle™ system bus controller.

Reduced time to market
Reduced development risk
Improved system performance
Simplified SoC integration
