Linux Solution
Full-Stack Linux Intelligent IoT Platform
In the field of intelligent device development, choosing a stable, open, and vibrant software platform is the cornerstone of project success. Linux, as the operating system of choice for global embedded devices and IoT applications, continues to empower countless industries with its unparalleled maturity, rich open-source software ecosystem, and strong community support. Today, a complete ecosystem built on the Linux 6.6 LTS kernel and the Yocto Project is delivering an unprecedented development experience through the RTL8730E high-performance platform.
We offer not just a chip, but a full-stack, standard Linux-based software development environment. From kernel drivers to application frameworks, from the build system to security modules, the RTL8730E platform fully inherits decades of technological excellence accumulated by Linux, allowing you to focus on product innovation rather than low-level adaptation.
Industrial “toolkit” for building custom Linux operating systems
Linux's vitality stems from its continuously evolving kernel and highly flexible build methodology.
- Leading-edge & Stable Linux Kernel: The platform is built around the Linux Kernel 6.6 LTS (Long-Term Support), ensuring your device starts with the latest hardware support, performance optimizations, and security hardening from day one. We provide a smooth upgrade path to newer kernels like 6.18, ensuring long-term product competitiveness and technical vitality.
- Standardized Build with Yocto Project: We provide a deeply optimized Board Support Package (BSP), seamlessly integrated with the Yocto Project, the industry-recognized framework for building embedded Linux. Developers can freely customize the system and directly access a vast repository of verified software packages via the OpenEmbedded repository, enabling "recipe-based" rapid integration. This significantly improves development efficiency and system maintainability.
Standard Wireless Protocol Stacks Connecting Everything
The strength of the Linux ecosystem lies in its comprehensive and deep integration of global standard protocols. The RTL8730E, as a connectivity core, perfectly hosts these mature solutions.
Mature Linux Wi-Fi Subsystem
- Advanced Wi-Fi 6 Support: The chip driver is deeply integrated into Linux's cfg80211 framework, delivering a complete, standardized Wi-Fi 6 connectivity experience from the radio layer up to applications.
- Advanced Peer-to-Peer Technology: The protocol stack natively supports Wi-Fi Direct (P2P) and Wi-Fi Aware, providing standardized Linux implementations for fast device pairing, low-power discovery, and instant data transfer between devices.
- Complete Network Management Chain: Supports configuration via standard connection managers like ConnMan, paired with WPA Supplicant for enterprise-grade security authentication. This architecture ensures a consistent management experience with any Linux distribution.
Widely Adopted Bluetooth & Next-Gen Connectivity Protocols
- Dual-Mode Bluetooth based on BlueZ: Integrates the standard Linux BlueZ protocol stack, fully supporting Classic Bluetooth Audio and Bluetooth Low Energy (BLE), and is ready for next-generation LE Audio and its LC3 codec.
- Native Integration into Smart Home Ecosystems: The platform integrates Matter and OpenThread protocol stacks, enabling your device, based on the common Linux foundation, to seamlessly join the interconnected world built by global tech giants.
Powerfull Multimedia & Graphics
Linux hosts the most mature software frameworks for handling complex multimedia and graphics applications. The powerful audio/video hardware of the RTL8730E is fully unleashed within this ecosystem.
- Professional Audio/Video Processing Pipeline: Supports the two core multimedia frameworks, GStreamer and FFmpeg, enabling easy construction of complex applications ranging from A/V playback and streaming to real-time processing. The audio service layer integrates modern PipeWire or PulseAudio for professional management of multiple audio streams.
- Complete High-Performance Graphics Display Stack: From the kernel-level DRM/KMS (Direct Rendering Manager / Kernel Mode Setting) driver to widely used lightweight graphics libraries at the application layer like LVGL, provides a complete solution for building everything from simple interfaces to complex interactive animations. Developers can create smooth, visually appealing graphical user interfaces based on this.
Building Full-Chain Voice Algorithm Solution
In the pursuit of ultimate user experience today, deploying the core capabilities of intelligent voice interaction on the device locally has become a key trend for high-end smart devices. Our Linux platform deeply integrates the self-developed AIVoice Offline AI Solution, providing a complete, reliable, and flexible foundation for local voice processing.
- Audio Front-End (AFE): Integrates advanced algorithms like Acoustic Echo Cancellation (AEC), Beamforming, and Noise Suppression to ensure clear capture of voice commands even in complex acoustic environments.
- Keyword Spotting (KWS): Accurately detects preset wake words, enabling low-power, high-accuracy always-on readiness.
- Voice Activity Detection (VAD): Intelligently determines the start and end of speech, effectively filtering out silent periods and ambient noise.
- Offline Automatic Speech Recognition (ASR): Completes the recognition and understanding of specific command words locally on the device, achieving instant response with zero network dependency.
Building the Foundation for Device Security
Providing Hardware-Level Trust & Isolation for Linux
The platform leverages Arm® TrustZone® technology to create a hardware-protected Trusted Execution Environment (TEE) for the Linux system.
- Secure World: Runs critical security services like secure boot verification, key management, and device identity authentication independently in this environment. Its code and data are isolated by hardware, completely separated from the Linux system.
- Linux World (Normal World): Runs the full-featured general-purpose operating system and applications freely, maintaining complete openness and flexibility.
Providing Standardized Security Service Interfaces via OP-TEE
The platform integrates the open-source OP-TEE (Open Portable Trusted Execution Environment) solution, providing a complete set of standardized, easy-to-call security APIs for applications on the Linux side.
- Secure Service Calls: Linux applications can request the TEE to perform operations like encryption/decryption, secure storage, and secure authentication via standard interfaces, without needing to understand underlying hardware details.
- Hardware Crypto Engine Acceleration: Cryptographic operations can be accelerated by the chip's built-in hardware crypto engine, significantly reducing CPU resource usage on the Linux system while enhancing security.
- Trusted Secure Storage: Provides hardware-based secure storage space for Linux applications to protect device-unique credentials, user keys, etc. Even if the storage medium is physically read, the data cannot be leaked.
Advantages
Based on the mature Linux kernel and Yocto build system, provides a fully pre-integrated software suite from Wi-Fi/Bluetooth stacks and multimedia frameworks to development tools, significantly reducing low-level adaptation efforts. This allows you to focus on core application innovation and accelerate time-to-market.
The multi-core heterogeneous architecture (Cortex-A + Cortex-M) of the RTL8730E platform provides ample computing power for the Linux system. Combined with Wi-Fi 6, professional audio hardware, and MIPI display interfaces, it ensures smooth system operation.
The hardware-level security architecture based on Arm TrustZone and OP-TEE builds a multi-layered security defense for the Linux system, covering chip boot, system operation, and data storage.
