Abstract

This work extends RHCS with the capability to link to additional libraries at runtime just by specifying the libraries' filenames. The software components defined in the libraries are made available to the system by means of prototypes. By retaining the abstract interfaces from RHCS we are now able to dynamically compose a complete control framework at runtime without referring to any implementation of the components as building blocks. Also it is possible to extend and adapt the software at runtime according to the needs of reconfigured hardware, or even switch to emulation mode without recompiling the software. Additional components can be build and loaded independently of the existing runtime. This leads to the possibility to build the control software from a textual database describing the hardwares properties. Another possibility would be to use a graphical editor to compose the components to a running system. The performance overhead due to software indirection is monitored and the correctness of architecture is verified by implementing a functional prototype.

可重构的硬件控制软件使用匿名库

这项工作扩展了RHCS，使其能够在运行时通过指定库的文件名链接到其他库。在库中定义的软件组件通过原型对系统可用。通过保留来自RHCS的抽象接口，我们现在能够在运行时动态地组成一个完整的控制框架，而无需引用组件的任何实现作为构建块。此外，还可以根据重新配置硬件的需要在运行时扩展和调整软件，甚至可以在不重新编译软件的情况下切换到仿真模式。可以独立于现有运行时构建和加载其他组件。这使得从描述硬件属性的文本数据库构建控制软件成为可能。另一种可能性是使用图形编辑器将组件组合到正在运行的系统中。通过实现功能原型，监测软件间接导致的性能开销，验证体系结构的正确性。
