| ARM Introduces Cortex-M4 Core for Digital Signal Controllers |
By BDTI, 7/29/2010
 This spring, ARM added the Cortex-M4 digital signal controller (DSC) to its processor core line-up. This product brings digital signal processing capabilities to ARM’s microcontroller core line (the Cortex-M family). At the Embedded Systems Conference in San Jose in April, NXP demonstrated a prototype Cortex-M4-based chip running at approximately 150 MHz. In June, Freescale announced its Kinetis line, also based on the Cortex-M4. ST Micro and Texas Instruments have also announced their intentions to use the Cortex-M4.

| APTX Expands Apt-X Audio Codec Lineup, Sells Hardware Division |
By BDTI, 5/20/2009
 At the recent AES convention in Munich, audio technology house APTX (formerly APT, Audio Processing Technology) announced that it is developing a new, scalable variant of its “apt-X” audio compression algorithm. The new codec is called “apt-X Scalable,” and is intended to be used as a single-codec solution in products that process a range of audio inputs, such as mobile devices that include voice, music, ringtones, and other forms of audio.

| BDTI Releases Benchmark Results for Toshiba's Venezia Platform |
By BDTI, 4/22/2009
 BDTI recently completed a benchmark analysis of the Toshiba MeP “Media embedded Processor” core and “IVC2” SIMD coprocessor, both of which are used in Toshiba’s Venezia mobile multimedia platform.
The MeP is a licensable core that is intended to be used as a building block in multi-core, multimedia-oriented SoCs, typically with multiple MeP cores on a chip. Each MeP core can be customized with specialized instructions, co-processors, and memory sizes.

| Fraunhofer Stealthily Advances Compression Technologies |
By BDTI, 9/17/2008
 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 millions of people use every day—a little thing called MP3. Fraunhofer also co-developed AAC and has been involved in developing the H.264 video codec, along with other codecs. But unlike the audio algorithm experts at Dolby, whose brand is visible on home audio equipment and whose name is nearly synonymous with high-quality audio, Fraunhofer has kept a relatively low profile. That’s because it has a somewhat unusual business model and history.

| Avnera releases ASSPs for wireless audio applications |
By BDTI, 11/14/2007
 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, scientific and medical uses. Avnera claims a typical range of 45 feet, with longer range if an optional external power amplifier is used.
