A Flexible Profiling Sub-System for Reconfigurable Logic Architectures

In recent years, embedded applications have been characterized by increasingly stringent requirements, both from functional and non-functional point of view. This led to the adoption of complex hardware platforms (multi-core and many-core architectures), able to guarantee high computational power with low energy consumption and reduced footprint. An efficient characterization of these platforms can be problematic, given the large number of hardware resources and the complexity of software applications. For this reason, the need for a runtime analysis support should be taken in account during the design phase (a design "for monitorability"). This paper introduces "Adaptive Profiling Hardware Sub-system" (AIPHS), a hardware profiling tool supporting the development of runtime monitorable systems. Two different multicore platforms are considered in order to evaluate AIPHS functionalities: an asymmetric dual-MicroBlaze system and a quad-Leon3 system supporting symmetric multiprocessing.
