Accelerated processor claims top DSP performance
Analog Devices has released its ADSP-TS101S TigerSHARC processor to production operating at an industry-leading 2.4GMACS and 1.8GFLOPS.
As part of the Home Theatre Connect DTS-610, the SHARC processor powers the market's first implementation of DTS Interactive, a new real-time consumer audio encoder technology.
"Our Home Theatre Connect DTS-610 removes the limitations in handling DRM-protected content that traditionally restrict media centre PCs from blending seamlessly with other components", said Steven Erickson, Vice President of Audio for Creative.
"ADI's SHARC processor provides the encoding performance we need to produce the first hardware encoding device that allows the PC to converge with the home entertainment centre".

Processor enables flexible 3G basestation design
Analog Devices has collaborated with Ericsson to develop a programmable baseband platform based on the TigerSHARC processor for WCDMA basestations.
"We selected the SHARC processor because it offered a complete solution - including key software and system components - that helped us reduce development time and keep costs low", Erickson added.
"Once again Analog Devices has brought to market the newest premium audio technology from DTS to enable leading technology companies like Creative to deliver products with an unmatched user experience".
"Today's announcement extends DTS's reach into the emerging market space where PC and consumer electronics devices converge", said Brian Towne, Senior Vice President of Consumer/Pro Division of DTS.
Playing back DRM-protected content on a PC, such as purchased MP3 files and DVD audio disks, typically requires the PC's digital audio output connector be shut off in order to prevent the content from being copied.
However, owners of the content who simply want to send the files to a multichannel receiver for enjoyment on a home theatre system are prevented from doing so.
Now with the Home Theatre Connect DTS-610, users are able to send music, a movie, or PC game content through their Sound Blaster sound card's analogue outputs and have it encoded in real time with DTS Interactive.
The content is then digitally distributed to a home theatre system for playback.
The Home Theatre Connect DTS-610 is now available for an estimated street price of US $99.99.
"Creative's Home Theatre Connect DTS-610 brings a satisfying listening experience to the home, providing the end customer with quality and value", said Mike Haidar, General Manager, Software and Systems Technology, Analog Devices "With its high performance, high level of system integration, and ability to process the latest DTS Interactive technology, the SHARC processor is in tune with Creative's exacting design specifications".
Creative's Home theatre Connect DTS-610 uses ADI's ADSP-21262, a member of the third-generation SHARC processor family.
The processor uses the high-performance SHARC core that supports execution of 32bit fixed-point and 32/40bit floating-point arithmetic formats.
In audio applications, the single-instruction, multiple data (SIMD) mode effectively doubles the processor performance.
The SHARC processor ADSP-21262 provides large on-chip dual-ported memory (including 2Mbit of on-chip dual-ported SRAM and 4Mbit of mask programmable ROM memory) to enable sustained processor and I/O performance without the need for external memory.
System I/O is achieved through six full-duplex serial ports, four timers, a 16bit parallel port, a serial peripheral interface (SPI), 22 zero-overhead direct memory access (DMA) channels delivering fast data transfers without processor intervention, and an innovative digital applications interface (DAI) offering complete software control through its signal routing unit (SRU).
Creative supplies digital entertainment products for PC users.
Famous for its Sound Blaster sound cards and for launching the multimedia revolution, Creative is now driving digital entertainment on the PC platform with products like the MuVo and Zen portable audio players.
DTS decoders are in virtually every major brand of 5.1-channel surround processors, and there are more than 300 million DTS-licensed consumer electronics products available worldwide.
A pioneer in multichannel audio, DTS technology is in home theatre, car audio, PC and game console products, as well as DVD-Video, Surround Music and DVD-ROM software.
DTS audio products are featured on more than 24,000 motion picture screens worldwide.
Additionally, DTS provides imaging technology and services for the motion picture industry.
