实时系统领域对计算密集型工作负载的需求正在增长，这需要更强大的硬件来满足。便宜但功能强大的多核硬件似乎是一个很好的解决方案，但这些处理器往往缺乏良好的可预测性。操作系统可以隐藏重新获得可预测性的措施，比如缓存管理，但要做到这一点，需要对硬件有很好的了解。这些度量的一个问题是，它们通常不具有可移植性，并且需要进行大量工作才能使它们适应新平台。我们希望从抽象的体系结构描述中生成特定于平台的代码，以获得可移植的操作系统，该操作系统能够适应现代硬件的特定硬件属性，从而提供可预测的执行环境。
The demand for computationally intensive workloads in the domain of real-time systems is growing which needs to be satisfied with more capable hardware. Cheap but powerful multi-core hardware seems to be a good solution but these processors often lack a good predictability. An operating system can hide measures to regain the predictability, like cache management but to do so a good knowledge of the hardware is required. A problem with these measures is that they are usually not portable and require a lot of work to adapt them to new platforms. It is desirable to generate the platform-specific code from abstract architecture descriptions to get a portable operating system that adapts itself to the specific hardware properties of modern hardware to provide a predictable execution environment.
