RNS based logarithmic adder
The operation of logarithmic addition was always eclipsed with heavy volumes of look-up tables. So with a goal to reduce the ROM size, an elegant and novel technique for logarithmic addition using RNS (Residue Number System) is demonstrated in this paper. To formulate this technique, the properties of Finite Fields and Finite Rings are exploited. A multiple base logarithm has been defined first...

متن کاملDesigning RNS and QRNS full adder based converters
A systematic graph-based methodology for designing optimal VLSI RNS (Residue Number System) converters from binary system to RNS to quadratic RNS (QRNS) and conversely, using full adders as the basic building block is introduced. The design methodology derives array architectures starting from the algorithm level and ending up with the bit level design. This methodology can be considered as a u...
متن کاملA logarithmic-depth quantum carry-lookahead adder
We present an efficient addition circuit, borrowing techniques from the classical carry-lookahead arithmetic circuit. Our quantum carrylookahead (qcla) adder accepts two n-bit numbers and adds them in O(log n) depth using O(n) ancillary qubits. We present both in-place and out-of-place versions, as well as versions that add modulo 2n and modulo 2n − 1. Previously, the linear-depth ripple-carry ...
متن کاملSingle Flux Quantum One-Decimal-Digit RNS Adder
Residue number system (RNS) arithmetic has a promising role for fault-tolerant high throughput superconducting single flux quantum (SFQ) circuits for digital signal processing (DSP) applications. We have designed one of the basic computational blocks used in DSP circuits, one-decimal-digit RNS adder. A new design for its main component, the single-modulus adder, has been developed. It combines ...
