Performance evaluation provides a reliable reference to optimization of design and choice of purchase for embedded systems devices. Based on analysis of evaluation methods, benchmark structure and performance metrics, an implementation design, including system model, software architecture and module partition, of a performance evaluation system for embedded system devices is presented in this paper, which automates loading and executing of benchmarks, acquiring and saving of performance data, and processing and analyzing of evaluation results. A method for adapting the evaluation system to varied hardware and software configurations and diverse benchmarks is detailed from view of software framework, benchmark management and data exchange. The experimental result proved its advantage of flexibilfty and adaptability.
