After the bottle-neck of the adaptive compile system for Dalvik being analyzed

according to the scenery when the threshold counter decrements to zero

a lot of waiting time will be caused by system initialization

the strategy based on threshold reset is introduced.According to some applications centralized with hot-spot codes

which will caused a great deal of compiling work to be suspended

a strategy of dynamic adaptive threshold based on a result feedback mechanism

is implemented.It could maximize the performance enhanced by the dynamic compilation scheme.Compared to the Dalvik before optimization

the experimental result based on the platform of Galaxy S of Samsung Corporation indicates that the execution efficiency of loop operations is improved by 7% on average after optimized by the threshold reset strategy

the execution efficiency of conditional jump operations and instruction dispatch are improved by 5% on average and 8% assisted by the dynamic adaptive threshold scheme.
