slugDesigning High Performance Adder Circuit Using Output Prediction Logic-Opl Technique
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2014, Vol 2, Issue 6
Abstract
With the continuously increasing demand for low power & high speed VLSI circuits the brain storming among the scientists, inventors & researchers to find the techniques required to design such high performance circuits is also increasing day by day. In the answer to this search several design techniques have been found. Output prediction logic-OPL technique is one of such newly introduced techniques. OPL is a technique that can be applied to conventional CMOS logic families in order to obtain considerable speedups. Speedups of two to three times over static CMOS logic are demonstrated for a variety of combinational circuits. When applied to static CMOS the OPL retains the restoring nature of underlying logic family. In case of OPL applied to the pseudo NMOS & domino logic, the problem of excessive power dissipation is solved & speedups more than static CMOS logic is obtained.
