The growing complexity of embedded systems makes their behavior analysis a challenging task. In this context, tracing appears to be a promising solution as it provides relevant information about the system execution. However, trace management and analysis are hindered by the diversity of trace formats, the incompatibility of trace analysis methods, the(More)
Transactional Memory (TM) is a new programming paradigm that offers an alternative to traditional lock-based concurrency mechanisms. It offers a higher-level programming interface and promises to greatly simplify the development of correct concurrent applications on multicore architectures. However, simplicity often comes with an important performance(More)
This paper presents performance evaluation and analysis of well-known HPC applications and benchmarks running on low-power embedded platforms. The performance to power consumption ratios are compared to classical x86 systems. Scalability studies have been conducted on the Mont-Blanc Tibidabo cluster. We have also investigated optimization opportunities and(More)
This work presents a debugging methodology for MPSoC based on deterministic record-replay. We propose a general model of MPSoC and define a debugging cycle targeting errors by applying temporal and spatial selection criteria. The idea behind spatial and temporal selection is to consider not the entire execution of the whole application but replay a part of(More)
Motivated by the increasing heterogeneity and complexity of MPSoC systems, we propose a component-based generic approach for MPSoC observation. We show that components help in observing all software levels from system to application. We present the EMBera prototype and relate our experience in implementing it on two different platforms: a Linux-based(More)
To facilitate and speed up the embedded software tuning process, the SoC-TRACE project aims at defining an advanced trace management software infrastructure. It is to tackle trace collection, trace analysis and reorganization, as well as trace visualization. Its goals include storage of terabytes of data, trace format independence, the application of(More)
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(More)
Trace analysis graphical user environments have to provide different views on trace data, in order to be effective in helping the comprehension of the traced application behavior. In this article we propose an open and modular software architecture, the FrameSoC workbench, which defines clear principles for view engineering and for view consistency(More)
