The increasing hardware and software complexity of embedded systems is a challenge for the design, debugging and optimization of applications. Benchmarking becomes a major technique in the validation of the correctness and in evaluating the performances of a system. However, as the number of benchmarking suites keeps increasing, it is a challenge to choose among benchmarks and fully understand the obtained results. For example, the Phoronix test suite contains about 200 test suites of which more than 70 test the CPU performance. A promising approach to understanding benchmark behavior is to use tracing. However, to provide useful information, developers need to choose what exactly to trace, choose a non intrusive tracing solution, manage big traces and succeed in analyzing the important quantity of captured data.
