Digital Voice Systems Inc. (DVSI) Introduces SIMD optimized vocoder libraries for x86 platforms
Westford, Mass – Digital Voice Systems, Inc. (DVSI) the recognized leader in the development of low-data-rate speech compression technology announces the availability of AMBE+2™ Enhanced Dual Rate vocoder libraries optimized for x86 processor platforms using Intel Streaming SIMD Extensions (Intel SSE.). Depending on the target platform these libraries are up to 50% faster than standard x86 libraries. This new addition to DVSI's high performance vocoder libraries allows x86 processors to run with fewer MIPS and gives customers the ability to increase overall system performance by reducing power requirements or increasing channel density.
With almost all modern x86 processors now incorporating single instruction multiple data instructions (SIMD) users get to reap the benefits of hundreds of additional high performance SIMD functions and operations. Designers can now take advantage of these benefits with DVSI’s optimized libraries for SSE and AVX. The SSE Library incorporates SSE2, SSE3, SSSE3, SSE4.1 to make processing 30-40% faster. Whereas, the AVX Library includes SSE2, SSE3, SSSE3, SSE4.1, AVX, AVX2 to deliver a 40-50% faster increase in performance.
DVSI is now delivering LMR and dual rate APCO P25 vocoders libraries optimized for SIMD x86 processors. The libraries are available for 32 and 64 bit Windows or Linux platforms. SIMD optimized libraries for other DVSI vocoders or custom SSE instruction sets may be supported upon request.
DVSI's patented AMBE+2™ Voice Compression Algorithm that can operate at virtually any data rate from 2.0 to 9.6 kbps. With this high degree of flexibility, the user can optimize speech and FEC rates to provide excellent voice quality with superior robustness to bit errors and acoustic background noise. The unparalleled performance of this vocoder technology has resulted in it being chosen as the standard for voice quality in Land Mobile Radio and Mobile Satellite Communications systems around the world.
"DVSI's SIMD optimized vocoder libraries increase x86 processor performance to provide our customers the flexibility to increase channel density or reduce system power consumption" said Bob Maher, DVSI's director of sales and marketing. "This enhanced performance allows engineers to design more channels into call recording systems, dispatch consoles, and base stations or develop more efficient digital mobile radios."
