Conventional digital circuits dissipate a significant amount of energy because bits of information are erased during the logic operations. Thus, if logic gates are designed such that the information bits are not destroyed, the power consumption can be reduced dramatically. The information bits are not lost in case of reversible computation. This has led to the development of reversible gates. This Paper introduces new synthesis approach called Exorlink which reduces quantum cost compared to the technique Disjoint Sum Of Products (DSOP) when used in the design of reversible circuits. The design is coded in VHDL, simulated using ISIM and synthesized using Xilinx ISE 10.1i for the device Spartan3E FPGA.
