Benefits
Leading edge connectivity and coexistence.
The architecture of handsets and other portable electronic devices is changing with the emergence of subsystems designed to specifically handle connectivity functions, and this wave of connectivity adoption is all about using multiple connectivity technologies in a collaborative manner to implement new features. CSR identified this evolution and the new CSR9000 provides leading edge connectivity and coexistence.New Coexistence Decision Logic
CSR’s coexistence solutions are at the forefront of solving application specific coexistence issues. CSR has designed a new Coexistence Decision Logic block in all of its chips. Each radio has its own Coexistence Decision Logic block. Blocks predict the probability of a collision occurring during the next activity, which are signalled by other CSR radios. A decision is then made to defer or abort the activity.World's highest performance Bluetooth
BlueCore7 offers the world’s highest performance Bluetooth implementation, and is compatible with Bluetooth v3.0 + HS. BlueCore7 technology also allows Bluetooth and FM radios to work without interference, either independently or together, to allow users to stream FM radio.Tied together by CSR Synergy
The CSR9000 feature set is tied together by CSR Synergy, CSR’s milestone embedded wireless systems software that offers over arching support for CSR’s connectivity and wireless communication standards. It enables advanced new use cases through the easy and efficient co-operation of multiple wireless standards, and is the world’s first host connectivity software to work in this way.
