Abstract 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,… More >
