Pbkp_redicting energy and performance overhead of real-time operating systems

Abstract:

We present a high-level method for rapidly and accurately estimating energy and performance overhead of Real-Time Operating Systems. Unlike most other approaches, which rely on Transaction-Level Modeling (TLM), we infer the information we need directly from executing the algorithmic specication, without needing to build any high-level architectural model. We distinguish two main components in our approach: rst, an accurate one-time pre-characterization of the main RTOS functionalities in terms of energy and cycles; second, the development of an algorithm to rapidly pbkp_redict the occurrences of such RTOS functionalities. Finally, we demonstrate the feasibility of our approach by comparing it against gate level for accuracy and against TLM for speed. We obtain a worst-case energy error of 12% against a mean speedup of 36X. © 2010 EDAA.
