Bluetooth chip includes DSP for audio enhancement
BlueCore5-Multimedia is CSR's most advanced silicon offering best in class audio for applications including high-end stereo and mono headsets.
Bluetooth chip runs sound processing suite
CSR has announced a new addition to its Extension Partner Programme of third party enhancements to its powerful DSP-based BlueCore5-Multimedia silicon.
BlueMedia enhanced DSP brings significant improvements to CSR's existing multimedia BlueCore silicon, which was launched 2 years ago.
BlueCore5-Multimedia includes a doubling of the processing power of the DSP coprocessor to 64MIPS.
The on-chip memory in BlueCore5-Multimedia has also been upgraded to 156Kbyte SRAM and improvements to the internal stereo analogue codecs now provide up to 90dB signal to noise ratio.

DSP-based Bluetooth adds speech enhancement
BlueCore5-Multimedia silicon now offers NXP Software's speech enhancement technology aimed at Bluetooth headsets, in-car hands-free kits and mobile phones.
The BlueCore5-Multimedia IC is aimed at the increasingly sophisticated Bluetooth accessory market including mono and stereo headsets, automotive systems and music players.
This chip combines a fifth generation Bluetooth core, and uses the BlueMedia enhancement to embed CSR's latest generation ClearVoiceCapture (CVC) technology for improved on-chip echo cancellation and noise suppression.
In addition the BlueMedia enhancements are sized to run a wider range of digital music compression and decompression codecs including MP3+, AAC, WMA3 and ATRAC, as well as new additional audio functions including voice recognition, text to speech synthesis and 3D-postitional surround sound.
Brian O'Rourke, Senior Analyst, InStat commented: "With its latest release addressing the multimedia market, CSR remains on the cutting edge of the Bluetooth silicon market".
BlueCore5-ROM features the fifth generation Bluetooth core as a stand-alone IC to give the lowest power consumption, cost and size in the industry, and is targeted for those applications, including the mobile phone, that already include a separate DSP coprocessor.
In this case CSR can provide the BlueMedia DSP software to run on the separate IC optimised to run in conjunction with CSR ICs.
BlueMedia on-chip DSP enhancements are also used in its BlueCore5 ICs to offer other non-Bluetooth radios for broadcast reception.
The first of these will be BlueCore5-FM, with FM radio embedded in the Bluetooth silicon.
This IC is targeted at those applications that are looking to reduce the cost, sise and power consumption of existing broadcast receivers at the same time as upgrading to include Bluetooth.
These features of BlueCore5 build on top of the now well-established Bluetooth v2.0+EDR (with faster 3Mbit/s data transfer rates).
CSR remains the only company supplying EDR silicon in volume and has already shipped over 5 million chips.
BlueCore5-ROM will start sampling from Q4 2005.
BlueCore5-Multimedia and BlueCore5-FM will start sampling in early 2006.
Glenn Collinson, cofounder and Sales Director, CSR commented: "BlueCore5 extends CSR's lead in Bluetooth with the first fifth generation Bluetooth solution with industry leading power figures as well as the first full support for the latest Bluetooth standard".
Collinson continued: "However, this generation marks a significant step towards our vision of BlueMedia".
"By putting more focus on our strong DSP architecture we can integrate more technologies with the Bluetooth radio, our customers can continue to improve their time to market even when the complexity of the modern device is exploding".
