| Triple Play DSP Chips and Boards for Developers |
Product developers are moving away from single-media VoIP chips to Triple Play chips and DSPs. Using Triple Play media processing products, Voice, Video, and Data can be processed simultaneously on a single DSP chip, using a single system, replacing single-media audio DSPs, VoIP DSPs and video DSPs. The result is a cost-effective and scaleable system allowing step-by-step migration from 'Voice only', to a 'full Voice and Video' system. It lowers the migration costs for equipment vendors, allowing them to integrate Triple Play solutions into their existing products. Triple Play DSP chips are intended for manufacturers of telecom equipment such as media gateways, media servers, IMS and CTI applications.
Surf Triple Play DSP software supports VoIP, Video, Audio, Fax and Modem simultaneously on a single DSP. It runs on TI 64x DSPs and supports, among others, G729, G711, G726, G723.1A, H263, MPEG-4, RTP, RTCP: RFC 3550/3551.
The Triple Play DSP Chips family provides a complete DSP solution for media over packet Triple Play telecom.
Surf's Triple Play DSP chip family offers a variety of DSP-level solutions for the development of telecom infrastructure applications, all of which are based on members of Texas Instruments' C64x™ DSP generation. Each member of the DSP family comprises a complete media processing solution, optimized for specific telecom voice, video, and fax/modem applications.
Surf DSP solutions are provided in a variety of chip types:
- Surf DSP-12 - based on TI TMS320C6412 for complete DSP Solution for Media over Packet Triple Play Applications
- Surf DSP-24 - based on TI TMS320C6424 for complete DSP Solution for Voice, Fax & Modem Applications
- Surf DSP-82 - based on TI TMS320C6455 or TMS320TCI6482 for complete DSP solution optimized for voice & video applications.
These DSPs are available on the following form factors:
- Advanced Mezzanine Card (AMC) for multiple DSPs on a DSP farm supporting high density carrier-grade applications
- PMC/PTMC for carrier grade applications
- PCI Express for robust enterprise-wide multimedia processing and CTI applications
- PCI for enterprise and CTI applications

DSP General Information
Digital Signal Processing (DSP) is the processing of signals in a digital representation. DSP development of digital signal processing dates from the 1960's. The introduction of the microprocessor in the late 1970's and early 1980's made it possible for DSP techniques to be used in a much wider range of applications.
Signal processing is the analysis, interpretation and manipulation of analog or digital audio, speech, music, image and video signals , among others. Processing of such signals includes storage and reconstruction, separation of information from noise, compression, and feature extraction.

DSP Chips, DSP Cards and DSP Boards
During the 1980's the increasing importance of DSP led several major electronics manufacturers (such as Texas Instruments ) to develop Digital Signal Processor chips – specialized programmable microprocessors with architectures designed specifically for the types of operations required in digital signal processing.
An important application of DSP is in signal compression and decompression. Although some of the mathematical theory underlying DSP techniques, digital filter design and signal compression, can be fairly complex, the numerical operations required actually to implement these techniques are very simple. The architecture of a DSP chip is designed to carry out such operations incredibly fast, processing hundreds of millions of samples every second, to provide real-time performance.
