Design of a 4-bit 2's Complement Reversible Circuit for Arithmetic Logic Unit Applications

摘要: Nowadays reversible circuit designing is the emerging area of research. This design strategy aims towards formation digital circuits with ideally zero power dissipation. In this paper we have proposed a new logic module to 4-bit binary 2"s complement circuit. using can be used other low loss Arithmetic Proposed been simulated ModelSim and implemented Xilinx Spartan2 FPGA platform. General Terms calculator. Keywordslogic circuit, Reversible gates. These designs are optimized on basis total number gates in design, garbage outputs macro statistics etc. Later highly for 2"complement calculator single SSMT gate. gate introduced paper. various arithmetic logical applications, but its application limited only. The organized nine sections. First section gives introduction concept. Section two brief fundamental concepts logic. Next introduces i.e. After that four conventional numbers discussed. five performed. Result analysis given six. Sections seven, eight give conclusion, acknowledgement references respectively. 2.
