RW-BT-BB - Bluetooth 2.1+EDR / 3.0 Baseband Controller
The RivieraWaves RW-BT-BB IP is a "classic" BR/EDR Bluetooth baseband controller IP qualified for Bluetooth 2.1+EDR and 3.0. It is listed as a qualified design component on the Bluetooth SIG website where PICS can be found. It is composed of a synthesizable Bluetooth hardware baseband core controller for integration into ASICs and FPGAs, driven by a portable and configurable firmware containing all protocol layers up to HCI.
The RW-BT-BB hardware baseband core controller, in charge of packet encoding/decoding and frame scheduling, 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 Link Controller (LC), Link Manager (LM) and Host Control Interface (HCI).
Compatible with the standard Bluetooth HCI, The RivieraWaves Bluetooth baseband controller can be used with any 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 host protocol stack and profiles, including the open source BlueZ.
The firmware is provided with reference platform drivers and with a small scheduler (or kernel OS) which is a small and efficient Real Time Operating System (RTOS), offering task management, inter-task communications, message (queues and events) management and timing management.
The RW-BT-BB baseband controller IP deliverable includes a hardware simulation test bench with regression test suit, synthesis scripts, and a user-friendly validation tool running under Windows or Linux allowing easy unit testing and regression at system level.
The RW-BT-BB baseband controller IP can be complemented with the RivieraWaves RW-BT-RF IP for a full Bluetooth solution.
