VoIP Outfitter, Netergy Microelectronics Announces Availability of the Audacity-VP7 Audio Compression Engine for Voice-over-Packet Applications.Business Editors/High-Tech Writers Embedded Processor Forum 2002 NOTE TO MEDIA: Photos are available in a Smart News Release(TM) on Business Wire's Home Page at www.businesswire.com and at www.newstream.com SAN JOSE, Calif.--(BUSINESS WIRE)--April 30, 2002 Santa Clara, Calif.-based Netergy Microelectronics, Inc.(TM) (www.netergymicro.com), a subsidiary of 8x8, Inc. (Nasdaq:EGHT), announced today the general availability of its newest audio compression engine, the Audacity(TM)-VP7. The VP7 is ideal for such applications as voice over IP, DSL DSL in full Digital Subscriber Line Broadband digital communications connection that operates over standard copper telephone wires. It requires a DSL modem, which splits transmissions into two frequency bands: the lower frequencies for voice (ordinary or cable, as well as up to 24-port enterprise voice gateways. Additional applications include digital loop carriers, echo cancellation cards, DSP (1) (Digital Signal Processor) A special-purpose CPU used for digital signal processing applications (see definition #2 below). It provides ultra-fast instruction sequences, such as shift and add, and multiply and add, which are commonly used in math-intensive resource cards and trunking gateways. STMicroelectronics, as an early adopter of this technology, has already incorporated the VP7 core into its STV STV Single Transferable Vote STV Star Trek: Voyager STV Samanyolu TV (Turkey) STV Satellite Television STV Scottish Television STV Stranglethorn Vale (World of Warcraft computer game) 0397 Voice-over-Cable co-processor. For the first time, Netergy will reveal the technical details of the Audacity-VP7 processor at this week's prestigious Instat/MDR Embedded Processor Forum (www.mdronline.com). Dr. Philip Bednarz, president and CEO (1) (Chief Executive Officer) The highest individual in command of an organization. Typically the president of the company, the CEO reports to the Chairman of the Board. of Netergy Microelectronics, Inc., said, "The Audacity-VP7 is a good example of Netergy's expertise in creating innovative architectures for the emerging Voice-over-Packet market. The VP7 represents the 7th generation of DSP engines designed by our team and can be integrated into custom semiconductor designs. What makes us unique in the VoIP space is that we supply not only the chips, but also our own operating system and complete VoIP application software. We can have our customers up and running in a matter of a few months with new VoIP products such as phones and gateways with the customers' own unique product feature set. We are pleased to offer such a powerful and flexible product as the Audacity-VP7 to the VoIP market." Architecture The Audacity-VP7 is based on a single instruction multiple data (SIMD (Single Instruction stream Multiple Data stream) A computer that performs one operation on multiple sets of data. It is typically used to add or multiply eight or more sets of numbers at the same time for multimedia encoding and rendering as well as scientific ) architecture that combines a RISC RISC in full Reduced Instruction Set Computing Computer architecture that uses a limited number of instructions. RISC became popular in microprocessors in the 1980s. engine with a highly parallel DSP coprocessor. The RISC engine functions as the main controller supplying flow control and address generation for the DSP section. It also controls the I/O and DMA controllers. The DSP section has an arithmetic logic unit See ALU. (ALU (Arithmetic Logic Unit) The high-speed CPU circuit that does calculating and comparing. Numbers are transferred from memory into the ALU for calculation, and the results are sent back into memory. Alphanumeric data are sent from memory into the ALU for comparing. ) and a multiply accumulate unit (MAC), each of which has dual 64-bit inputs and outputs. Each of the units can simultaneously perform four operations per cycle. The ALU can add, subtract, perform logical operations and transpositions, as well as 32-bit signed normalizations and bit shifting with saturation. The MAC performs four independent 16X16 multiply accumulate operations or four 32-bit addition operations each cycle. Performance The Audacity-VP7 performs 400 million multiply accumulates per second and has an overall performance of up to 5.3 billion operations per second, depending on the characteristics of the program coding. Software The Audacity-VP7 comes complete with Netergy's comprehensive list of audio processing components, including a set of precompiled ITU vocoders such as G.711, G.726, G.723.1, G.729a/b, G.728 and G.729E. Additional audio services offered are echo cancellation (G.165/G.168), DTMF (Dual-Tone MultiFrequency) The type of audio signals that are generated when you press the buttons on a touch-tone telephone. See also DMTF. DTMF - Dual Tone Multi Frequency detection/generation, voice activity detection (VAD (Value Added Dealer) Same as VAR. ), comfort noise generation (CNG), FAX/modem tone detection and three-way mixing capability.
