Design of a compact reversible fault tolerant field programmable gate array: A novel approach in reversible logic synthesis

摘要

This paper demonstrates the reversible fault tolerant logic synthesis for the Field Programmable Gate Array (FPGA) and its realization using MOS transistors. Algorithms to design a compact reversible fault tolerant n-to-2~n decoder, 4n-to-n multiplexers, a random access memory and a Plessey logic block of the FPGA have been presented. In addition, several lower bounds on the numbers of garbage outputs, constant inputs and quantum cost of the FPGA have been proposed. The comparative results show that the proposed design is much better in terms of gate count, garbage outputs, quantum cost, delay, and hardware complexity than the existing approaches.
