Texas Instruments Announces New Upper-Level Bluetooth Stacks from both TROY Wireless and Stonestreet One
Available on TMS320C54x(tm) Generation of DSPs;Developers Can Take DSP-Based Applications Wireless with New Software from TI DSP Third Party Partners
HOUSTON (July 31, 2002) - To meet the market's increasing demand for wireless products, TROY Wireless, a division of TROY Group, Inc. (NASDAQ: TROY), and Stonestreet One, both members of the Texas Instruments (TI) (NYSE:TXN) DSP third party network, today announced that they both have available standard Bluetooth upper-level software for TI's TMS320C54x generation of digital signal processors (DSPs). With the ability to port an upper-level Bluetooth stack to a programmable DSP, TROY Wireless and Stonestreet One are enabling developers to go wireless with their C54x(tm) DSP-based products, including applications such as consumer audio, headsets, hands-free cellular car kits, digital still cameras, Internet connectivity, medical monitors robotics and a wide range of other DSP-based products.
"In the growing market for wireless solutions, DSP-based systems represent an important area of expansion for Bluetooth connectivity," said Joyce Putscher, director, In-Stat/MDR. "The availability of Bluetooth upper-level stacks for TI DSPs will push wireless connectivity into a new range of application areas."
Bluetooth upper-level stacks for programmable DSPs
The new Bluetooth upper-level stacks provide a standard interface that links application-specific Bluetooth profiles with the C54x DSP host processor and effectively open up an entirely new range of Bluetooth applications. Traditionally, generic Bluetooth upper-level stacks have been available for development on RISC-type processors. However, programmable DSPs offer customers the added capability to utilize hundreds of off-the-shelf DSP-compliant algorithms, along with the Bluetooth stack, to develop complete and timely product applications. Running the stack directly on the DSP eliminates the need for a separate microprocessor and memory for the Bluetooth protocol processing, thereby reducing the cost, size, and power consumption of a DSP-based device. The ability to efficiently expand the portability of the Bluetooth standard for DSP-based products benefits customers as it enables designers to meet the high demand for wireless applications.
Both TROY Wireless' and Stonestreet One's Bluetooth profiles allow C54x-based customers to perform key functions, such as file synchronization, wireless serial port and LAN access-all of which are essential for wireless communications. These Bluetooth software solutions also work well with TI's current Bluetooth baseband and radio silicon offerings, BSN6040, BSN6030 and TRF6001, and the upcoming BRF6100.
"The new Bluetooth stacks from TROY Wireless and Stonestreet One complement TI's strategy of providing complete DSP solutions to our customers," said Dennis Barrett, TMS320C5000(tm) marketing manager, TI. "These stacks mean our customers will be able to Bluetooth-enable their DSP applications more quickly and seamlessly than ever before."
TROY WindStack(tm)
The TROY Wireless Bluetooth stack, WindStack, is Bluetooth version 1.1 qualified and is performance optimized to run on TI's C54x DSP devices. Designed for embedded C54x applications, the WindStack enables complete Bluetooth stack implementation and includes a majority of the profiles, a variety of application programming interfaces (API), documentation and a C54x software evaluation kit. In addition, TROY has designed WindStack according to the TMS320 algorithm standard to make it easy for customers to integrate it with other third party algorithms and to help reduce time-to-market.
"We chose the C54x generation for our Bluetooth solution because we feel the DSP market will be the next major opportunity for Bluetooth wireless communications and because TI is the world leader in DSP technology," said Patrick Dirk, chairman and CEO, TROY. "We knew it was very important to optimize our stack for TI's C54x and to make it easy for customers to quickly add other off-the-shelf eXpressDSP(tm) algorithms to reduce product development time."
Stonestreet One Bluetopia(tm)
Stonestreet One's latest release of Bluetopia is specifically designed and optimized for TI's eXpressDSP Reference Framework 3 (RF3). TI's Reference Frameworks, which are adaptable to a variety of customer applications, eliminate much of the initial low-level design decisions for the developer and allow them more time to focus on the code that differentiates their products. This release of Bluetopia is built on Stonestreet One's performance-proven DSP Bluetooth protocol stack, which is already being used by several customers and partners. Bluetopia is Bluetooth version 1.1 compliant, has a flexible memory footprint, is completely scaleable and includes a comprehensive API. The headset and hands-free profiles, which are crucial to the development of many DSP-based products, are included, along with other core and newly released profiles. Bluetopia is available for virtually every operating system and platform. "With this new release, Bluetopia will now allow customers to optimize the audio functionality of Bluetooth technology while enjoying seamless integration into their C54x applications," said Tim Reilly, chief technology officer, Stonestreet One. "That seamless integration will mean real time-to-market advantages when adding wireless connectivity to DSP systems, and developers who use Bluetopia can tap into the expertise of Stonestreet One's engineers, who designed, developed and now support Bluetopia."
About Bluetooth
Bluetooth is a low-cost, low-power, short-range radio that communicates data and voice in piconets, point-to-multipoint networks from 0-10 meters or up to 100 meters with an amplifier. Bluetooth uses a fast frequency-hopping spread spectrum technique utilizing the free, unlicensed, globally available 2.4-GHz ISM band. Bluetooth transfers data at up to 721 Kbps.
