As the design cycle for IC products continues to shorten, building a strong software ecosystem has become increasingly critical for developers. A robust ecosystem not only supports the chip's upstream and downstream development but also significantly reduces R&D costs and accelerates time-to-market. To meet customer demands, Zhongtianwei, along with its partners, actively enhances the software ecosystem around its independently developed CPU IP, offering a comprehensive range of tools and components tailored for various applications.
Zhongtianwei collaborates closely with leading operating system providers across different application domains. Together, they develop customized components and SDKs suitable for CK CPU-based systems, including real-time operating system kernels, CSI abstraction layers, security modules, OTA upgrade features, TCP/IP and IoT protocol stacks, file systems, and graphics engines. These solutions are designed to be modular, configurable, and adaptable, giving customers flexibility in their development processes.
In the field of the Internet of Things (IoT), general-purpose MCUs, high-performance computing, and security technologies, Zhongtianwei has made significant progress in ecological development:
**IoT Field:**
As an Alibaba IoT partner, Zhongtianwei integrates innovative and secure ID2 technology at the CPU level (supporting TEE) to provide cloud-integrated security features, ensuring data protection from the device to the cloud. The company has optimized security protocols, cloud integration, debugging capabilities, and performance, making it ideal for smart cities, home appliances, and travel applications. In collaboration with ZTE Microelectronics, Zhongtianwei launched the RoseFinch7100 chip for NB-IoT security, alongside an MCU development board supporting NB-IoT functions. Additionally, it provides an IoT RF interface IP solution based on CK CPU to support the MCU+AliOS+RF ecosystem.
**General MCU Field:**
Zhongtianwei has successfully integrated with embedded lightweight OS ecosystems, such as FreeRTOS, uCOSIII, Zephyr, Nuttx, RT-Thread, and others. It supports multiple downstream SOC chips and connects with mainstream middleware and application systems via the CSI interface, simplifying ecosystem sharing and reducing development time. This approach improves software quality and speeds up service deployment.
**High-Performance Field:**
Zhongtianwei actively engages with the global Linux community, optimizing toolchains, kernels, and base libraries. It also performs hardware-software integration for common middleware and applications, laying a solid foundation for Linux ecosystem adoption. Using the Buildroot compilation environment, the company provides full Linux systems, including cross-compilation toolchains, root filesystems, kernel images, and system components. All key open-source components have been updated to the latest versions, enabling developers to leverage the most recent advancements.
**Security Field:**
To address growing security concerns in IoT and networked devices, Zhongtianwei has developed a trusted processor framework using TEE and anti-physical attack technologies. It offers a comprehensive security solution covering trusted boot, image signing, secure storage, data encryption, access control, and device authentication. In 2017, Zhongtianwei joined the Global Platform, contributing to the development of international security standards. It also partners with Shenzhen Nuichuang Xinan to offer professional security certification services.
**Development Tools Support:**
To enhance user experience, Zhongtianwei optimizes compiler toolchains, simulators, debuggers, and runtime libraries, improving code efficiency and performance. It offers two IDE environments: CDS for high-end applications and CDK for low-end MCU development, providing users with a more intuitive and efficient development process.
**Collaboration with Partners:**
Zhongtianwei works closely with industry leaders like AliOS and RT-Thread to build a robust software ecosystem. For example, it has developed a multi-level device platform based on AliOS Things, meeting the growing demand for IoT solutions. Similarly, it collaborates with RT-Thread to provide reliable and scalable development support for embedded systems.
