The multiplication operation is present in many parts of a digital system or digital computer, most notably in signal processing, graphics and scientific computation. With advances in technology, various techniques have been proposed to design multipliers, which offer high speed, low power consumption and lesser area. Thus making them suitable for various high speeds, low power compact VLSI imp...

The sustained growth in VLSI technology is fuelled by the continued shrinking of transistor to ever smaller dimension. The benefits of miniaturization are high packing densities, high circuit speed and low power dissipation. Binary multiplier is an electronic circuit used in digital electronics such as a computer to multiply two binary numbers, which is built using a binary adder. A fixed-width...

Many electronic voting protocols assume the voter votes with some computing device. This raises the question whether a voter can trust the device he is using. Three years ago, Chaum, and independently Neff, proposed what we call bare-handed electronic voting, where voters do not need any computational power in the voting booth. Their protocols have a strong unforgeability guarantee. The price f...

The Booth multiplication algorithm produces incorrect results for some word sizes, when it is extended for higher radix, fixed-point multiplication. We present a modification of the Booth algorithm that produces correct results when the radix is any power of 2 and the multipliers are of any size.

Fisheries catches from Pacific Island coral reefs are rarely recorded in official statistics. Reconstruction of catch estimates with limited hard data requires interpolation and assumptions, justifiable only by the unsatisfactory alternative of continued substitution of zero catches, a common policy interpretation for ‘no data’. Uncertainties associated with reconstructions are high, requiring ...
