RivieraWaves Bluetooth PlatformsPrint this page

The RivieraWaves Bluetooth IP family offers a comprehensive suite of platforms for embedding Bluetooth connectivity into SoCs/ASSPs, with solutions for Low Energy Bluetooth Smart, Dual Mode Bluetooth Smart Ready and Classic BR/EDR Bluetooth.

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.

The RivieraWaves Bluetooth platforms incorporate a hardware baseband controller coupled with a software stack and an optional RF/modem block. In addition, CEVA has multiple RF partners to help address deployment on various foundries and processes nodes; RF partners include CSEM, Catena, Maxscend, IMEC, Orca, Silicon Vision and others.

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.

Bluetooth Smart

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 machine–machine communications.

Compatible with the BLE hallmark feature of the Bluetooth 4.2 specification, the Bluetooth Smart IP consists of a hardware baseband controller coupled with a complete software stack including Profiles.

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 Smart Ready

Also known as Bluetooth Dual Mode, incorporating Classic Bluetooth & Bluetooth Low Energy, this 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.

Compatible with the Bluetooth 4.2 specification, it consists of a hardware baseband controller coupled with a software stack up to the standard HCI interface, and an optional modem+RF transceiver. The standard HCI ensures that the Bluetooth Smart Ready 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 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 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, …) 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 Classic Bluetooth IP is aligned with the Bluetooth Smart Ready IP, minus the BLE-specific aspects. It may be used standalone or combined with RivieraWaves Wi-Fi IP.

It consists of a hardware baseband controller coupled with a software stack up to the standard HCI interface and an optional modem+RF transceiver. 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.
