In the process of embedded systems modeling and performance evaluation, the performance indicators, such as average delay and CPU occupancy rate, are often need to be analyzed and evaluated. In this paper, the method for performance evaluation has been proposed, and the library function for performance evaluation based on SystemC language has been designed. The library function is designed for evaluating performance parameters, calculating expectations and confidence interval, and terminating the simulation when the performance indicators meet the accuracy requirements. In this paper, the performance evaluation of embedded speech recognition systems by using the library function and the method proposed was introduced in detail. For validating the correctness and practicality of the library function further, the library function has been also used in the performance evaluation of wireless AP systems, as well as in performance evaluation of complex embedded systems based on SystemC. It is of great value for extending the library of SystemC.
