Bluetooth 5.3 Low Energy Baseband Controller, software and profiles
The Ceva-Waves BLE hardware baseband controller core, in charge of packet encoding/decoding and frame scheduling, is complemented by a hardware AES128 encryption engine for real time encryption/decryption of the packets.
The firmware is composed of the Link Layer(LL) and Host Control Interface (HCI). It is provided with reference platform drivers and with a small task scheduler offering task management, inter-task communications, message (queues and events) management and timing management, for use as standalone or integrated into other real time OS. For LE Audio applications, it supports the ISO feature.
For a more comprehensive solution, the Ceva-Waves BLE baseband controller IP is complemented with:
The combined Ceva-Waves BLE firmware and Ceva-Waves BLE host protocol stack and profiles form a highly flexible solution supporting 3 different configurations:
A processor agnostic turnkey fully integrated platform with embedded open source RISC-V processor is also proposed as a cost effective and short time to market alternative solution.
The Ceva-Waves BLE host protocol stack and profiles can also be used with any Bluetooth low energy HCI controller IC.
For LE audio applications, Ceva-Waves Bluetooth IP is well complemented by the Ceva Sound solutions including the Ceva-BX1/2 audio/voice DSPs, ClearVox voice processing software package, Whispro speech recognition software package and a comprehensive list of CODECs and other sound processing software packages. The HillCrest Labs MotionEngine is another complementary software package optimized for touch and motion detection in headsets and earbuds.
