主　　题：Crosstalk energy efficiency register reallocation green compilation 

摘      要：As nanoscale processing becomes the mainstream in IC manufacturing,the crosstalk problem rises as a serious challenge,not only for energy-efficiency and performance but also for security requirements.In this paper,we propose a register reallocation algorithm called Nearby Access based Register Reallocation(NARR)to reduce the crosstalk between instruction buses.The method includes construction of the software Nearby Access Aware Interference Graph(NAIG),using data flow analysis at assembly level,and reallocation of the registers to the software.Experimental results show that the crosstalk could be dramatically minimized,especially for 4C crosstalk,with a reduction of 80.84%in average,and up to 99.99%at most.
