RivieraWaves Bluetooth PlatformsPrint this page

CEVA, with the RivieraWaves Wireless Connectivity IP platforms, is the only IP provider offering a complete suite of Bluetooth IPs plus a wide portfolio of RivieraWaves Wi-Fi IP platforms for 802.11a/b/g/n/ac for integrating wireless connectivity into IoT SoCs/ASSPs.

The RivieraWaves Bluetooth IP family covers Bluetooth low energy (BLE), Bluetooth dual mode (BTDM) and Bluetooth Classic (BT2.1+EDR). Advanced features coupled with low power remain at the heart of the platforms as the Bluetooth standard evolves to Bluetooth 5.

The RivieraWaves Bluetooth IP platforms consist of a hardware baseband controller, plus a feature-rich software protocol stack. For Bluetooth low energy, this protocol stack encompasses the Link Layer up to the GAP/GATT plus a comprehensive set of Services and Profiles. For Bluetooth dual mode, this protocol stack presents an industry standard HCI interface. A flexible radio interface allows the platform to be deployed with either RivieraWaves RF or various partners’ RF IP, enabling optimal selection of foundry and process node.

The software stack is easily portable to the customer’s choice of embedded processor, such as the CEVA-TeakLite-4, ARM® Cortex-M™series, ARC®EM family, AndesCore™ family, Cortus APS family and others.

The Bluetooth IPs are provided with an optional FPGA platform plus a comprehensive GUI validation tool for manual testing and automatic execution of test scripts for laboratory testing.

The RivieraWaves Bluetooth platforms are complemented in many applications by CEVA’s extensive portfolio of audio/voice solutions and Always-On sensor hub solutions, based around the CEVA-TeakLite-4 DSP core.

The RivieraWaves Bluetooth family

The RivieraWaves Bluetooth IP family consists of:

Bluetooth Low Energy

This provides a very low power, low MIPs & low gate count platform for applications requiring single mode Bluetooth Low Energy (BLE), e.g. smartwatches, hearing aids, wearable sensors for medical /sports (heart rate, glucose, temperature), remote controls, toys, environment sensors, location beacons and many other Internet of Things applications.

The hardware baseband controller is provided as a Verilog IP package. It performs packet encoding/decoding and frame scheduling and is complemented by a hardware AES128 encryption engine.

The software stack is provided as a C code IP package. It consists of Link Layer (LL), L2CAP, ATT, SMP, GAP/GATT, services and profiles.

Bluetooth Dual Mode

The RivieraWaves Bluetooth Dual Mode IP incorporates Classic Bluetooth & Bluetooth Low Energy. It provides an optimised solution for next generation 'combo' SoCs for cellular phones, tablets, audio accessories and other products. It may be used standalone or combined with RivieraWaves Wi-Fi IP.

The hardware baseband controller is provided as a Verilog IP package. It performs packet encoding/decoding and frame scheduling for both Classic (BR/EDR) and Low Energy (BLE) Bluetooth. It is complemented by a CVSD hardware codec with a-law/u-law/linear PCM samples converter for voice applications.

The Controller software stack is provided as a C code IP package. It is composed of the BR/EDR Link Controller (LC), LE Link Layer (LL), Link Manager (LM) and Host Control Interface (HCI). The standard HCI ensures that the Bluetooth IP can be used with any compliant Host software stack (and profiles), including BlueDroid™ (as per Android™), BlueZ™, IVT, OpenSynergy, Motorola Solutions, A&W and others.

The modem+RF transceiver, available in various process nodes, is designed for easy integration into digital SoC. The digital portion (modem and RF controller) is provided as an RTL IP package. The modem which performs the GFSK and EDR modulation/demodulation is also available as a standalone IP package. The analogue portion (ADC/DAC, PLL, LNA, PA, mixer, LDO, etc.) is available as GDSII and schematics IP packages.

Bluetooth Classic

Often referred to as 2.1+EDR/3.0, this provides a solution for applications requiring the still popular classic Bluetooth, such as audio headsets and game controllers. The Bluetooth Classic IP is aligned with the Bluetooth Dual Mode IP, minus the BLE-specific aspects. It may be used standalone or combined with RivieraWaves Wi-Fi IP.

The hardware baseband controller is provided as a Verilog IP package. It performs packet encoding/decoding and frame scheduling. It is complemented by a CVSD hardware codec with a-law/u-law/linear PCM samples converter for voice applications.
