DSP-enabled Bluetooth Audio IP Platform for TWS Earbuds and Wearables BluebudTM is a self-contained, feature-rich IP platform to streamline the development of True Wireless Stereo (TWS)...
The RivieraWaves™ Bluetooth IP family is a comprehensive suite of IPs and platforms for embedding Bluetooth 5.3 – both Bluetooth Low Energy and Bluetooth dual mode versions – into SoC/ASSP. Together with the Wi-Fi IP family, the Bluetooth IP family forms part of CEVA’s popular and production-proven RivieraWaves Wireless Connectivity portfolio.
Each solution consists of a hardware baseband controller, a PHY (modem + RF), and a feature-rich software protocol stack, fully integrated into a processor- and operating-system-agnostic platform to make deployment easier. A turnkey fully integrated processor agnostic platform is also available. For both Bluetooth Low Energy and Bluetooth dual mode, the software protocol stack encompasses the controller stack below the industry-standard HCI interface (Link layer, Link Controller/Manager) and the host stack above HCI , as well as a comprehensive list of services and profiles:
|Bluetooth Classic Profiles||Bluetooth LE Profiles|
· Full Generic Audio Framework (GAF) with Common Audio Profile (CAP), Hearing Aid Profile (HAP), Telephony & Media Audio Profile (TMAP), etc
· Apple MFi LEA
|Medical/ HealthCare Suite||· Blood Pressure, Health Thermometer, Glucose / Continuous Glucose Monitor, Weight Scale, etc|
|Sport & Fitness Suite||· Cycling & Running Speed, Cycling Power, Heart Rate|
|Mesh||· With Lighting and Generic Models|
|Miscellaneous||· SPP, OBEX, SDAP, PAN, GAP, PBAP, HID, Apple iAP2, Google Fast Pair, etc||· Alert Notification, Phone Alert Status, HID, Environmental Sensing, Location and Navigation, etc|
The software protocol stack is easily portable to many embedded processors, including ARM® Cortex-M™ series, ARC®EM family, RISC-V, AndesCore™ family and others.
A flexible radio interface enables the solutions to be deployed with either RivieraWaves RF or various partners’ RF IPs, enabling optimal selection of both foundry and process node.
An optional 802.15.4 support add-on is also available for licensing. The RivieraWaves 15.4 offering includes a MAC hardware accelerator driven by its 802.15.4 software driver, complemented by an 802.15.4 O-QPSK modem. Each of the RivieraWaves 15.4 MAC and modem can be provided as stand-alone IPs or combined with the RivieraWaves Bluetooth baseband controller and modem respectively. It supports the Google open-source implementation of Thread and any 3rd party Zigbee protocol stack. It complies with Matter requirements, the foundation for connected things combining 15.4/Thread, BLE and Wi-Fi for unified smart home devices.
An optimized Wi-Fi & Bluetooth coexistence interface with Packet Traffic Arbiter is also available for smooth simultaneous operation.
The Bluetooth IPs are provided with a comprehensive GUI validation tool for manual testing and automatic execution of test scripts in laboratory tests. A reference FPGA platform is also available as an option.
The comprehensive RivieraWaves Wireless Connectivity IPs and platforms simplify development and deployment of wireless connectivity by:
