Abstract :

Nowadays, in the trend of strong growth of embedded software technology, the optimization of embedded software has an important role. The evaluation and optimization of embedded software in the design phase brings many benefits. In this paper, we propose a new method to optimize embedded software based on generating simulation code of functions from model. The embedded software is modeled according to the different task flow diagrams. Each task in the diagram is specified input, output and is estimated according to the set of basic operations. Each basic operation is mapped to a code snippet by language selected. We define the Domain Specific Language which is used to design task flow diagrams. Based on Text Template Transformation Toolkit, the executable simulation code of programs will be generated from the correspondence diagrams. We run these programs on the actual device to get the information of performance, power consumption and occupied memory size. Then we build the objective functions and do multi-objective optimization for embedded system based on Pareto principle
