Designing adaptable processors by extending static compilation techniques with dynamic architectural reconfiguration.

专门为给定应用程序设计处理器通常涉及两个不同的阶段。第一阶段识别应用程序的计算密集型部分，以确定处理器的构建块。在下一阶段，应用程序的功能通过编译实现。由于每个应用程序都有自己不同的计算要求和性能要求，因此根据所执行的应用程序的类型，这两个阶段都会有所不同。因此，在设计周期的这两个阶段，根据特定应用程序的要求进行适应性是至关重要的。这种两阶段的适应性在当今的方法中通常是不存在的。更常见的情况是，处理器体系结构具有固定的组成，并使用静态编译技术。我们提出了一种动态自适应的体系结构，该体系结构由可定制的编译流程指导。整个过程是由应用程序驱动的，其中静态编译技术通过动态架构重新配置进行了扩展。运行时反馈机制引入了对体系结构和编译过程的修改。

Designing a processor specifically for a given application typically involves two distinct phases. The first phase identifies the computationally intensive parts of the application to determine the building blocks of the processor. In the next phase, the application’s functionality is realised through compilation. As each application has its own diverse computational demands and performance requirements, variations in both these phases are to be expected depending on the type of application executed. Consequently, adaptability according to application-specific requirements is essential in both these phases of the design cycle. This two-phase adaptability is typically absent in present day methodologies. More often the processor architecture has a fixed composition and uses static compilation techniques. We propose a dynamically adaptable architecture that is steered by a customisable compilation flow. The entire process is application-driven, where static compilation techniques are extended with dynamic architectural reconfiguration. A run-time feedback mechanism introduces modifications to the architecture and the compilation process.
