Abstract
FPGA structures are widely used as they enable early time-to-market and reduced non-recurring engineering costs in comparison to ASIC designs. Interconnections play a crucial role in modern FPGAs, because they dominate delay, power and area. Multiple-valued logic allows the reduction of the number of interconnections in the circuit, hence can serve as a mean to effectively curtail the impact of interconnections. In this work we propose a new look-up table structure based on a low-power high-speed quaternary voltage-mode device. The most important characteristics of the proposed architecture are that it is a voltage-mode structure, which allows reduced power consumption, and it is implemented with a standard CMOS technology. Our quaternary implementation overcomes previous proposed techniques with simple and efficient CMOS structures. Moreover, results show significant reductions on power consumption and timing in comparison to binary implementations with similar functionality.
