An Effective Heuristic-Based Approach for Partitioning

الملخص EN

As being one of the most crucial steps in the design of embedded systems, hardware/software partitioning has received more concern than ever.

The performance of a system design will strongly depend on the efficiency of the partitioning.

In this paper, we construct a communication graph for embedded system and describe the delay-related constraints and the cost-related objective based on the graph structure.

Then, we propose a heuristic based on genetic algorithm and simulated annealing to solve the problem near optimally.

We note that the genetic algorithm has a strong global search capability, while the simulated annealing algorithm will fail in a local optimal solution easily.

Hence, we can incorporate simulated annealing algorithm in genetic algorithm.

The combined algorithm will provide more accurate near-optimal solution with faster speed.

Experiment results show that the proposed algorithm produce more accurate partitions than the original genetic algorithm.
