There’s a German research institution that many people outside of Europe have never heard of. Well, there are probably lots of German research institutions that many people have never heard of, but this particular one, Fraunhofer, was instrumental in developing a technology that
VeriSilicon has released a licenseable DSP core, the ZSP800, and an associated development platform, VZ.AudioHD, optimized for “HD” audio applications. The term “high definition audio” can mean different things to different people. For example, in 2004
Dolby , based in San Francisco, CA, has acquired audio compression specialist Coding Technologies . Dolby is well-known for its AC-3 audio compression algorithm (also known as Dolby Digital), used worldwide in cinema sound and more recently accepted for audio for digital television in North
Avnera has released a set of application-specific standard product (ASSP) chips aimed at the audio market. Avnera’s chips, implemented in CMOS, transmit and receive stereo audio (close to CD quality) over the 2.4 GHz wireless ISM band assigned internationally for industrial,
Introduction Are you designing a system that involves audio? Maybe an audio product or a product with an audio subsystem? Here are some tips and tricks that may help you. Designing audio systems and debugging audio presents some interesting challenges. Sound is ruthlessly

It’s generally accepted that, for processing engines, there is a trade-off between efficiency and generality. The more a chip is geared towards a specific application, the more efficient it’s likely to be (in terms of speed, energy consumption, and cost). On one end of

While nearly all signal processing applications require some degree of software optimization, some applications require a sophisticated, multi-tiered optimization approach in order to meet their performance goals. To obtain the most efficient code, DSP software must be optimized at four

At the Consumer Electronics Show last month I was struck (not for the first time) by the number of consumer electronics products that rely on digital signal processing—at this point, nearly all of them. In fact, so many of today's products incorporate digital signal processing-based
On January 3rd, Freescale announced the first dual-core members of its Onyx family of audio DSPs. The first two chips in the family, the DSP56720 and DSP56721, feature two DSP5636x cores operating at 200 MHz. The chips mainly target high-definition audio processing in
