基于RISC-V平台openEuler系统的COMO构件技术移植与应用

Transplantation and Application of COMO Component Technology Based on RISC-V Platform and openEuler System

随着云计算、物联网技术的发展,边缘计算模式开始兴起. RISC-V开源指令集架构和openEuler开源操作系统正在逐渐形成一个开放、灵活、不断演进和架构包容的软件生态体系,为边缘计算应用的构建提供了良好的软硬件创新平台.然而,在其之上的支持面向边缘计算的软件开发环境、开发框架和工具链等基础设施尚不够完善. COMO是解决C++软件资产复用的构件化技术,将COMO技术与RISC-V、openEuler结合有助于RISC-V、openEuler生态在新的软件技术架构上发展.本文提出了在基于RISC-V架构和openEuler操作系统的软硬件平台上进行COMO构件程序运行与开发环境移植的思路和方法,并通过实验证明了COMO构件技术与RISC-V指令集架构和openEuler操作系统的兼容性和可行性;通过一个简单的实例介绍COMO的ServiceManager框架在边缘计算中的应用,在为面向云计算与物联网的边缘计算应用提供XaaS服务的构件化程序开发模式的方向上进行了有益的探索.

With the development of cloud computing and Internet of Things(IoT) technology, the edge computing mode begins to emerge. On the basis of the open-source instruction set architecture RISC-V and openEuler operating system(OS), an open, flexible, evolving, and architecture-inclusive software ecosystem has been gradually formed, which provides a good innovative software and hardware platform for the construction of edge computing applications.However, the infrastructure such as software development environments, frameworks, and toolchains for edge computing is not yet complete. The component model(COMO) is a component technology that solves the reuse issue for C++software and assets, and the combination of which with RISC-V and openEuler is conducive to the development of RISCV and the openEuler ecosystem in a new software development architecture. Therefore, this study proposes the method of operating the COMO program and transplanting the development environment on the software and hardware platform based on RISC-V and openEuler OS, and an experiment proves the compatibility and feasibility of COMO with RISC-V and openEuler OS. In addition, a simple example is introduced for the application of COMO’s ServiceManager framework in edge computing. The work makes a useful exploration in the component-based development mode of providing XaaS services for edge computing applications oriented to cloud computing and IoT.
