This paper proposes an inexact Baugh-Wooley Wallace tree multiplier with novel architecture for 4:2 compressor optimised realisation using reversible logic. The proposed has ±1 Error Distance (ED) and 12.5% Rate (ER). efficacy of the logic based is measured in scales Gate Count (GC), Quantum Cost (QC), Garbage Output (GO) Ancilla Input (AI). able to reduce metrics GC, QC, GO AI by 50%, 15%, 25%...

In this paper we describe a new complex multiplier based on Distributed Arithmetic (DA) using an overturned-stairs adder tree (OS-tree). The OS-tree yields the same speed as the optimal Wallace tree, but has the advantage of a regular layout. A 17×13 complex multiplier is implemented with MietecTM 0.35 μm standard CMOS technology. It can execute 30 Mmult./s and dissipate about 15 mW at 25 Mmult...

Simon Saunders and David Wallace are attempting to use a modified form of David Lewis's analysis of personal fission to support the thought that prior to undergoing Everett branching an informed subject can be uncertain about which outcome s/he will observe. I argue that the seductive appeal of the idea is an illusion arising out of failure to distinguish between the provenance and reference of...

Amethod is given for calculating the strict minimummessage length (SMML) estimator for 1-dimensional exponential families with continuous sufficient statistics. A set of n equations are found that the n cut-points of the SMML estimator must satisfy. These equations can be solved using Newton’s method and this approach is used to produce new results and to replicate results that C. S. Wallace ob...

This paper investigates how market structure a¤ects e¢ ciency and several dimensions of liquidity in an asset market. To this end, we generalize the searchtheoretic model of …nancial intermediation of Darrell Du¢ e et al. (2005) to allow for entry of dealers and unrestricted asset holdings. Keywords: bid-ask spread, execution delay, liquidity, search, trade volume JEL Classi…cation: G11, G12, G...

Aim Nearly 150 years ago, T. H. Huxley modified Wallace’s Line, including the island of Palawan as a component of the Asian biogeographic realm and separating it from the oceanic Philippines. Although Huxley recognized some characteristics of a transition between the regions, Palawan has since been regarded primarily as a peripheral component of the Sunda Shelf. However, several recent phylogen...

Fast multiplication can be constructed by combining the tree structure of multiplication's addition, i.e. Wallace tree, with the parallel on-they conversion to have a multiplication without using any carry propagation adder at the end. This parallel on-they conversion speeds up the conversion of redundant binary to conventional binary. With the delay of n 4 , we can have the conversion from red...

This paper describes the pipelined architecture of high-speed modified Booth Wallace Multiply and Accumulator. The proposed multiply and accumulate circuits are based on the Booth algorithm and the pipelining techniques, which are most widely used to accelerate the multiplication speed. A 32-bit MAC Unit is designed in which the multiplication is done using the Modified Booth Wallace Multiplier...
