Reversible Architecture of Computer Arithmetic

Reversible Architecture of Computer Arithmetic

Reversible logic plays an important role in emerging low power designs and quantum computing. This paper presents an efficient way to realize reversible arithmetic circuits especially targeting toward reversible arithmetic logic unit (RALU). In literature for reversible logic, not a significant advancement is found in integrating both logical and arithmetical functions, commonly known as arithm...

Reversible computer engineering and architecture

There exists a set of reversible primitive modules that may be combined according to a set of simple rules to create larger systems, which are themselves reversible primitive modules. These modules may be combined to create a fully reversible, universal computer. I describe techniques for creating reversible primitive modules from simple switches, such as conventional CMOS transistors, and the ...

Reversible arithmetic logic unit

Quantum computer requires quantum arithmetic. The sophisticated design of a reversible arithmetic logic unit (reversible ALU) for quantum arithmetic has been investigated in this letter. We provide explicit construction of reversible ALU effecting basic arithmetic operations. By provided the corresponding control unit, the proposed reversible ALU can combine the classical arithmetic and logic o...

Partial Reversible Gates(PRG) for Reversible BCD Arithmetic

IEEE 754r is the ongoing revision to the IEEE 754 floating point standard and a major enhancement to the standard is the addition of decimal format. Furthermore, in the recent years reversible logic has emerged as a promising computing paradigm having its applications in low power CMOS, quantum computing, nanotechnology, and optical computing. The major goal in reversible logic is to minimize t...
