Audio DSPs waltz through multichannel
decoding
The next generation in the Aureus family of audio digital signal processors is ideal for applications requiring audio decoding and simultaneous high-speed encoding.
Continuing to drive audiophile levels of sound quality to affordable consumer price points, Texas Instruments has introduced the next generation in its Aureus family of high-performance audio digital signal processors (DSPs) for applications requiring multichannel decoding, including audio/video (A/V) and DVD receivers, home-theatre-in-a-box systems (HTIBs), set-top boxes, mini-compos, high-definition televisions (HDTV) and automotive navigation/multimedia systems These devices also are ideal for applications requiring audio decoding and simultaneous high-speed encoding, such as DVD recorders, home music servers and automotive jukeboxes

Bluetooth and FM coexist in harmonious RF chip
The BlueLink 6.0 platform combines the industry's best performance Bluetooth wireless technology with high fidelity FM stereo and mono performance on a single chip.
Gigabit Ethernet transceiver is flexible interface
A six-channel gigabit Ethernet transceiver provides a full-featured, flexible interface in datacommunications and telecommunications equipment.
With 50% performance improvement at the same price point as the previous generation of Aureus products, the 300MHz TMS320DA710 and 250MHz TMS320DA708 deliver one of the industry's most versatile, cost-effective DSPs and development environment for high performance, high-quality multichannel audio applications.
For example, a complete 7.1 system, including AC3 or DTS decoding, Dolby ProLogic IIx or NEO:6 matrix decoding, bass management and delay, takes only 22% of the available performance of a DA710 processor.
With nearly 80% of the available performance for customisation and differentiation, OEMs can implement product-differentiating features.

Quasiresonant controller has green credentials
An innovative green-mode power management circuit is claimed to significantly improve energy efficiency in consumer electronic systems and AC power adapters.
Architectural enhancements specifically designed for high-performance audio processing enable efficient use of the extensive headroom available on DA7xx devices.
New mixed-precision instructions allow for higher quality bass management and equalisation algorithms without the performance impact of using double-precision.
An audio-optimised dual data movement accelerator (DMAX) performs efficient nonsequential external memory accesses and circular buffer management, improving the performance of long delay line algorithms, such as reverb.
Additionally, the CPU core and memory subsystem were enhanced and the amount of parallel processing was increased, resulting in higher performance in audio applications.
DA7xx devices are backed by production-quality software, including TI's Performance Audio Software Library, an end-to-end system software solution.
The Performance Audio Software Library is based on TI's XDAIS algorithm standard, which allows OEMs and third parties to create plug-and-play algorithms.
Numerous third parties are supporting the Performance Audio Library, including Audyssey, SRS Labs, Waves and Neural Surround.
This enables OEMs to more efficiently develop and customise audio algorithms, getting products to market faster, quickly spinning derivative products by adding new features, and reducing development costs in general.
The DA7xx is the second generation in the Aureus family of audio processors and confirms TI's commitment to the multichannel audio market.
The first-generation Aureus DSP (DA6xx) was selected by Dolby for its Pro Logic IIx enhanced surround sound development platform and has been designed into equipment by the world's leading audio OEMs, including: Alpine, Clarion, JVC, Onkyo and Harman Kardon.
The DA7xx family is code compatible with TI's previous generations of the Aureus family and built on TI's C6000 DSP architecture.
The DA7xx devices leverage TI's investment in C6000 tools including the award-winning Code Composer Studio IDE.
Developers can get started today with DA710 and DA708 EVMs from Momentum Data Systems.
The EVMs include digital I/O, multichannel analogue I/O and all the other system components required to prototype a typical A/V receiver system.
"TI's Aureus family of DSPs continues to push the boundaries of quality and performance for home theatre processing", said Brian Towne, Senior Vice President at DTS.
"DTS is pleased that TI has designed a high performance and cost effective processor package capable of implementing our new DTS-HD technology".
"DTS-HD will feature 7.1 lossless audio and is backward compatible with existing DTS decoders".
"DTS is proud to count TI as one of its key launch partners".
Currently sampling, both devices are slated for volume production in Q3 2005.
The 250MHz TMS320DA708 costs $13.52 each and comes in a 144-pin TQFP package.
The 300MHz TMS320DA710 costs $21.63 and comes in a 256 BGA package, both in 10,000 unit or more quantities.
