As the design cycle for IC products continues to shorten, building a robust software ecosystem has become increasingly vital for developers. Promoting the development of a comprehensive software ecosystem not only benefits the chip industry but also enhances collaboration across the entire supply chain. To meet customer demands, reduce development time, and lower R&D costs, Zhongtianwei, along with its partners, is actively working to enrich the ecosystem around its independently developed CPU IP.
Zhongtianwei collaborates closely with leading operating system providers and developers across various application domains. By supporting mainstream operating systems, the company develops a wide range of components and SDKs tailored for CK CPU-based systems, including real-time operating system kernels, CSI abstraction layers, security modules, OTA update components, TCP/IP and IoT protocol stacks, file systems, and graphics engines. These solutions offer configurable and customizable options, giving customers flexible choices to suit their specific needs.
In the field of the Internet of Things (IoT), general-purpose MCUs, high-performance computing, and security, Zhongtianwei has made significant progress in ecological construction:
**Internet of Things:**
As an Alibaba IoT partner, Zhongtianwei integrates innovative and secure ID2 technology at the CPU level (with TEE support) to provide cloud-integrated security features. This ensures data protection from the device to the cloud, creating a secure environment. The company has optimized security technologies, cloud integration, debugging capabilities, performance, and real-time functionality, which are now widely used in smart cities, home appliances, and travel applications.
For the NB-IoT market, Zhongtianwei and ZTE Microelectronics jointly developed the RoseFinch7100 chip, the first commercially mass-produced IoT security chip. They also launched an MCU development board with NB-IoT support. Additionally, Zhongtianwei provided an IoT RF interface IP solution based on CK CPU to support the ecosystem of MCU + AliOS + RF.
**General MCU Field:**
In the general-purpose MCU domain, Zhongtianwei connects with embedded lightweight operating systems and supports top RTOS microkernels such as FreeRTOS, uCOSIII, Zephyr, Nuttx, and RT-Thread. It also integrates mainstream middleware and application systems via the CSI interface, making ecosystem sharing simple and efficient. This significantly reduces product development time, improves software quality, and accelerates application deployment.
**High Performance Field:**
Zhongtianwei actively engages with the global Linux community, optimizing toolchains, kernels, and base libraries. It also performs hardware-software integration on commonly used middleware and applications. Using Buildroot, the company provides a complete Linux compilation environment, allowing users to compile cross-compilation toolchains, root filesystems, kernel images, boot images, and system components. Zhongtianwei has updated key components like the toolchain, kernel, and C library to the latest open-source versions, enabling developers to easily access the latest advancements.
**Security Area:**
To address security concerns in IoT and networked devices, Zhongtianwei has developed a trusted processor framework. Through TEE and anti-physical attack technologies, it addresses internal and external threats comprehensively. The company has also upgraded its software security technologies to deliver a full-suite solution for trusted boot, image signing, secure storage, data encryption, access control, and device authentication. In 2017, Zhongtianwei joined the Global Platform, an international standards organization, to develop security chip standards. It also partners with Shenzhen Nuichuang Xinan (OSR) to provide professional security support services.
**Development Tools Support:**
To enhance user experience, Zhongtianwei optimizes the compiler toolchain, simulator, debugger, and runtime library for the CPU architecture. It offers two IDE development environments—CDS for high-end applications and CDK for low-end MCU applications—to cater to different use cases and improve development efficiency.
**Collaborating with Partners to Build Software Ecosystems:**
- **Partner: AliOS**
As an Alibaba IoT partner, Zhongtianwei has created a multi-level device development platform based on AliOS Things, meeting the technical requirements of the IoT era and the growing market demand.
- **Partner: RT-Thread**
Zhongtianwei works closely with RT-Thread to support and expand the ecosystem, ensuring compatibility and performance for a wide range of applications.
