Abstract: As the crucial design steps in reconfigurable system development process, the results of the hardware/soft- ware task partitioning directly affect the performance of reconfigurable system. Most of the current hardware/software task partitioning only consider the partitioning results of the application or the algorithm, ignoring the overheads of the FPGA configuration and communication, resulting in the actual result is not satisfactory. I}his paper presented a hard- ware/software task partitioning methods based on performance evaluation,which generates the hardware/software task partitioning results of reconfigurable system by evaluating and testing the overhead of computing, configuration and communication of日'GA, combined with improved simulated annealing algorithm. The experimental results show that the partitioning method has good accuracy and faster convergence speed.
