MPSoC （multi-processor systems on-chip） are going to be the leading hardware platform featured in embedded systems, The complexity of multimedia applications implemented on MPSoC and the requirements of users complicate the designer＇s job to conceive and deliver efficient systems in the shortest time. MPSoC dedicated to specific embedded applications are facing constraints of performance and cost. In this context, in order to improve the performance of these systems, we propose a methodology for dynamic task migration in dedicated MPSoC. This methodology aims to improve the performance of execution and also reduction of energy consumption. We propose in this paper, an estimation of the real-time energy （line）. This approach is structured on four steps：（1） modeling software; （2） mapping and execution; （3） performance evaluation; （4） migration. We have using the Soclib tool to determine performance estimation of migrating software task to hardware component. Experiments on MJPEG decoder are made to illustrate the efficiency of our approach in performance estimation.

关键词： MPSoC migration soft/hard dynamic migration MJPEG decoder.

The performance degradation mechanism of ceramic fuel cell with NCAL(Ni_(0.8)Co_(0.15)Al_(0.05)LiO_(2))as symmetrical electrode and GDC as electrolyte in H2 is *** is found that under the condition of 550◦C and constant current density of 0.2 A⋅cm^(-2),the output voltage of the cell is about 1.005 V in the initial 10 h and remains relatively *** 10 h,the voltage of the cell began to decrease gradually,and by 50 h,the voltage had decreased to 0.522 *** results testing electrochemical performance of the cell and characterizing the cell materials before and after test using SEM,TOF-SIMS and FTIR indicate that the distribution of Li_(2)O/LiOH/Li_(2)CO_(3)compounds generated from NCAL anode in the cell plays a vital role in significantly improving the ionic conductivity of electrolyte and gas tightness of the *** dynamic migration of molten salt destroyed the continuity of molten salt in the cell,which in turn adversely impacted the ionic conductivity of electrolyte,gas tightness of the cell,and electrochemical reactions on both sides of the cathode and *** finally lead to the degradation of the cell performance.
