抜粋

Multiple power domain design architectures have been studied for the power-efficient FPGAs. But, most of these researches pay attention on the clustered logic block's finegrain power gating which increases the FPGA size significantly. This paper presents a fast placement algorithm for coarsegrain FPGAs architecture, by which the circuit with multiple power domains is mapped into several regions for low power consumption. Each region uses one or several sleep transistors in order to conserve leakage energy. Using the CAD framework, we discuss the power efficiency of sleep region FPGA architecture by using the benchmarks assumed in multiple power domains. Simulation result shows that 9.1% power consumption of FPGA can be reduced on average by the proposed placement algorithm, compared to the traditional algorithm. Furthermore, when the dual power domains are individually power-on and -off, our proposed method can reduce the power more than 20%.
