Abstract: Firstly,system′s hardware and software are model unified.Then an estimated time performance method based on dynamic programming,and a linear-weight sum method to construct the fitness function′ way are presented,and combining them with genetic algorithm to solve hardware/software partitioning problem.Finally,simulates the illustration,and the result shows that the method can solve multi-object optimization design effectively.
