In this paper, we present a new methodology to rapidly explore the large design space encountered in hardware/software systems. The proposed methodology is based on a fast and accurate estimation approach. It has been implemented as an extension to a hardware/software codesign flow to enable the exploration of a large number of multiprocessor architecture solutions from the very start of the design process. It takes advantage of both system and RT levels of abstraction, and combines both static and dynamic analysis techniques, in order to obtain the best trade­off between speed and accuracy. The effectiveness of this approach is illustrated by a significant application example. Experimental results indicate strong advantages of the proposed methodology
