Overview

CEVA offers the RivieraWaves Bluetooth Smart Ready IP, a Bluetooth Smart ready 4.2 baseband controller IP compatible with classic BR/EDR Bluetooth and Bluetooth low energy specifications. Compatible with Bluetooth 2.1+EDR, 3.0, 4.0, 4.1 and 4.2, it is composed of a synthesizable Bluetooth hardware baseband controller core for integration into SOCs/ASSPs, driven by a portable and configurable firmware containing all protocol layers up to HCI. The hardware baseband controller core , in charge of packet encoding/decoding and frame schedulig, is complemented by a CVSD hardware codec with a-law/u-law/linear PCM samples converter for voice applications. The firmware is composed of the BR/EDR Link Controller (LC), LE Link Layer (LL), Link Manager (LM) and Host Control Interface (HCI). Compatible with the standard Bluetooth HCI, the RivieraWaves Bluetooth Smart Ready baseband controller can be used with any Bluetooth Smart Ready 4.2 host software protocol stack and profiles, either split around the HCI so that the lower layers and upper layers can run on different processors or systems, or combined together to run on the same processor to make a fully hosted solution. The customer is free to choose any 3rd party Bluetooth Smart Ready 4.2 compatible host protocol stack and profiles, including BlueDroid per Android BlueZ VT, OpenSynergy, Motorola Solutions, A&W and others. The firmware is provided with reference platform drivers and with a small scheduler (or kernel OS) which is a small and efficient Real Time task scheduler, offering task management, inter-task communications, message (queues and events) management and timing management, for standalone use or integration into other real time OS. The RivieraWaves Bluetooth Smart Ready baseband controller IP deliverable includes a hardware simulation test bench with regression test suit, synthesis scripts, and a user-friendly validation tool running under Window or Linux allowing easy unit testing and regression at system level. The RivieraWaves Bluetooth Smart Ready baseband controller IP can be complemented with the RivieraWaves Bluetooth Smart Ready RF IP for a full Bluetooth Smart Ready solution.
