Flash memory is optimised for Bluetooth
Cambridge Silicon Radio and Fujitsu have been working together to develop Flash memory optimised for Bluetooth requirements.
The single-chip multimedia Bluetooth devices are based on CSR's high-performance Kalimba DSP coprocessor, which supports third party enhancements while maintaining very low power consumption and high audio quality for both voice and music applications.
To date, CSR is the only company capable of offering such a powerful combination, of hardware and high quality third-party software enhancements, to designers allowing them to create high-performance, customisable devices without needing to compromise on critical elements such as power consumption.
Bob Ackmann, CEO, Acoustic Technologies, explained: "CSR leads the field for Bluetooth wireless technology".
"We are delighted to work together to offer the SoundClear Multi-Mic audio solution and the added value it provides to CSR customers using its silicon platform".
"Our affiliation with the world leader in Bluetooth has allowed us to reach a global audience of designers and will allow the industry to move forward with better quality voice communications, making Bluetooth an even more attractive prospect to end-users".
The ATS6000MM SoundClear technology uses two microphones to eliminate noise and achieve a higher level of sound quality.
The software automatically adjusts its calculations according to environmental conditions, the speaker's voice and the quality of the line connection.
The software operation can also be optimised by end-product designers according to the type of plastics, transducers and desired audio configuration adopted.
Murray concluded: "Consumers are demanding more of their wireless devices in terms of performance, audio quality and power consumption".
"BlueCore-Multimedia with SoundClear caters for this trend and provides a powerful base for future evolution".
