CSR today launched its fifth generation of BlueCore, the Bluetooth hardware and software solution with more than 55% of the market today. CSR also today launched its BlueMedia enhancements using new DSPs embedded inside the ICs to bring both improved audio performance and added radio functionality.

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.

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 co-processor. In this case CSR can provide the BlueMedia DSP software to run on the separate IC optimised to run in conjunction with CSR ICs.
