DSP Bluetooth upper-level software
announced
For TI's TMS320C54x generation of DSP, Bluetooth upper-level software from Troy Wireless and Stonestreet One is an interesting development
Although generic Bluetooth upper-level stacks are usually used for development on RISC-type processors, programmable DSPs offer customers the added capability to use hundreds of off-the-shelf DSP-compliant algorithms, along with the Bluetooth stack, to efficiently develop product applications Running a stack directly on the DSP removes the need for a separate microprocessor and memory for the Bluetooth protocol processing

Data buffer has dual multiplexer
Texas Instruments has introduced the industry's first 0- to 4-Gbps data buffer/signal conditioner with a dual multiplexer.
In turn this reduces 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.
Now, to meet an increasing demand for wireless products, Troy Wireless and Stonestreet One have developed standard Bluetooth upper-level software for TI's TMS320C54x generation of DSPs.

Texas Instruments has unveiled two new triple-output plug-in power solutions for asymmetric digital subscriber line (ADSL) applications.
With the ability to port an upper-level Bluetooth stack to a programmable DSP, these two members of the Texas Instruments DSP third party network are enabling developers to go wireless with their C54x DSP-based products.
These include applications such as consumer audio, headsets, hands-free cellular car kits, digital still cameras, Internet connectivity, medical monitors, robotics and many other DSP-based products.
Joyce Putscher, director, In-Stat/MDR says: "In the growing market for wireless solutions, DSP-based systems represent an important area of expansion for Bluetooth connectivity.
"The availability of Bluetooth upper-level stacks for TI DSPs will push wireless connectivity into a new range of application areas".
The new Bluetooth upper-level stacks provide a standard interface which can link application-specific Bluetooth profiles with a C54x DSP host processor and effectively open up a completely new range of Bluetooth applications.
Troy Wireless' and Stonestreet One's Bluetooth profiles both allow C54x-based customers to perform key functions, such as file synchronisation, wireless serial port and LAN access 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.
Dennis Barrett, TMS320C5000 marketing manager at TI, says: "The new Bluetooth stacks from Troy Wireless and Stonestreet One complement TI's strategy of providing complete DSP solutions to our customers.
"These stacks mean our customers will be able to Bluetooth-enable their DSP applications more quickly and seamlessly than ever before".
Stonestreet One's latest Bluetopia release is specifically produced for TI's eXpressDSP Reference Framework 3 (RF3).
It is available for virtually every operating system and platform.
TI's Reference Frameworks, which can be adapted to various customer applications, remove much of the initial low-level design decisions for developers and give more time to focus on the code that differentiates their products.
The latest Bluetopia release is built on Stonestreet One's proven DSP Bluetooth protocol stack, already being used by several customers and partners.
It is Bluetooth version 1.1 compliant, has a flexible memory footprint, is totally 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.
Tim Reilly, chief technology officer of Stonestreet One, says: "With this new release, Bluetopia will now allow customers to optimise the audio functionality of Bluetooth technology while enjoying seamless integration into their C54x applications.
"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".
The Troy Wireless Bluetooth stack, WindStack, is Bluetooth version 1.1 qualified and is performance optimised 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.
Troy has designed WindStack according to the TMS320 algorithm standard to make it easy for users to integrate it with other third party algorithms and to help cut time to market.
Patrick Dirk, chairman and CEO of Troy, says: "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.
"We knew it was very important to optimise our stack for TI's C54x and to make it easy for customers to quickly add other off-the-shelf eXpressDSP algorithms to reduce product development time".
