Aspect-Oriented SystemC-Based Performance Evaluation of Real-Time Embedded Software

This paper presents the methodology for performance analysis of real-time embedded systems specified on system level. We developed aspect-oriented extensions to the SystemC environment, that enable to include profiling code, as well as code modeling execution time, into the system specification. First, the specification woven with profile aspects is simulated in target environment and information about execution times is saved in a file. Next, the same specification is woven with simulation aspects, that use the information gained in previous step to simulate execution times. In this way accurate timed model of the system is obtained automatically.
