[ English | 简体中文 ]
openvela is an operating system specifically crafted for the AIoT industry, with a focus on being lightweight, standards-compliant, secure, and highly scalable. It has become the technology of choice for millions of IoT devices and AI gadgets, including smart watches, fitness bands, smart speakers, earbuds, smart appliances, and robotics.
The name "Vela" is originated from the Latin term for "sail," which is also the name of the constellation resembling a sail in the southern sky. We aspire to partner with developers and set sail on a voyage through the AIoT landscape.
-
Highly Scalable: openvela has been designed to be modular and scalable, allowing it to easily adapt to a wide range of IoT applications. It can fit in a small BLE module with 32KB RAM, and scale up to a powerful smart display device with 512MB RAM, highly scalable!
-
One-Stop Solution: Over the years, openvela has evolved into a powerful platform with comprehensive feature sets, making it a one-stop solution for various IoT applications. We consistently incorporate new functionalities to meet emerging needs. By leveraging openvela, manufacturers can significantly reduce their R&D costs and accelerate their product development cycles.
-
Mature Heterogeneous Computing Support: openvela offers top-of-the-line support for heterogeneous multi-core systems, featuring a seamless IPC mechanism between various processing units such as MCU, MPU, DSP, GPU, and NPU. Additionally, openvela provides an advanced RPC framework between openvela, Linux, and Android systems to enable hybrid OS leveraging strength from three systems.
-
Standard Compliant and High Portability: openvela Kernel is built upon Apache NuttX, which is often referred to as "tiny Linux". With this foundation, openvela achieves a high degree of conformity with the POSIX standard. Our team has been continually enhancing its POSIX compatibility, which has now reached an impressive 88%. Because of this standards conformance, software developed under other standard OSs (such as Linux) can be easily ported to openvela with minimum effort.
-
Comprehensive Connectivity Suite: openvela offers broad protocol support, including Bluetooth BR/EDR/LE, LE Mesh, WiFi, Matter, IEEE802.15.4, and LTE Cat1, Ethernet, CAN/LIN, etc. Additionally, it seamlessly integrates with Xiaomi HyperConnect protocols.
-
Rich Developer Tools: openvela offers a comprehensive suite of developer tools, including system monitoring, performance analysis, debugger, trace, crash dumb, and log analysis tools.
openvela supports a variety of architectures (ARM32, ARM64, RISC-V, Xtensa, MIPS, CEVA, etc.) and platforms. See the full list on the Supported Architectures and Platforms page.
