Design space exploration (DSE) is an important step before the physical level design of Field programmable gate arrays (FPGA). An optimum architecture is usually selected from the whole space. As the architecture parameters increase, the huge time cost to explore an exponentially increasing space makes this method unrealistic. We propose a novel predictive modeling approach called ECOMT to estimate...
An approach to estimate the performance of FPGA architectures is proposed based on semi-supervised model tree algorithm. The proposed approach avoids synthesizing, mapping, packing, placing and routing, which are essential steps in a traditional flow to obtain the performance of FPGA. Thus it is time efficient while the performance predicted maintains quite close to the result obtained through the...
Dual-output lookup tables (LUTs) are mainstream in the design of commercial FPGA products. A detailed exploration of architectural parameters of FPGAs based on dualoutput LUTs is presented. Different from traditional single-output LUT based architecture, “shared inputs” between the sub-LUTs is a new parameter specific to dual-output architecture. In this paper, we focus on the effect of ratio of shared...
