A Generic Component-Based Approach to MPSoC Observation

Observing the execution of MPSoC is a key activity in debugging and optimizing embedded applications. However, providing suitable observation tools becomes a real challenge with the fast evolution of embedded platforms. We propose a generic component-based approach which allows for partial and configurable MPSoC observation. Genericity is obtained by encapsulating specific embedded features and exporting a generic observation API. Partial observation is achieved by instantiating and attaching observation components only to the entities of interest: application modules, HW components or different levels of the SW stack. Configurability is related to the possibility to organize and parametrize observation treatments (data collection, filtering, storing) according to the target system. The approach has been validated in several application and platform contexts including an embedded platform built by STMicroelectronics.
