The PRiME Framework: Application- & platform-agnostic system management

Multi-core and heterogeneous processors in modern embedded platforms have increased in complexity to provide both high-performance and energy-efficient execution of applications.As a result, the runtime management and control of these platforms has become a non-trivial process with many different approaches being reported in the literature. In addition, applications have become increasingly dynamic to exploit these processors runtime adjustable parameters that can be tuned to optimise and influence their behaviour. These two challenges motivate the need for a consistent approach to runtime management that is cross-platform and generic in the support of applications. This abstract presents the PRiME Framework, a cross-layer framework that enables application- and platformagnostic runtime management by separating a system into three distinct layers connected by an API and cross-layer constructs called knobs and monitors. The motivation for the framework’s underlying concepts are discussed and its use is demonstrated with a range of platforms and applications.An open-source implementation of this framework has been released.
