ABSTRACT
The Itanium brand extends Intelâ„¢s reach into the highest level of computing enabling powerful servers and high- performance workstations to address the increasing demands that the internet economy places on e-business. The Itanium architecture is a unique combination of innovative features, such as explicit parallelism, predication, speculation and much more.
In addition to providing much more memory that todayâ„¢s 32-bit designs, the 64-bit architecture chan ....etc

Abstract.
Hyperspectral imagery is a new type of high-dimensional image data which is now used in many Earth-based and planetary exploration applications. Many efforts have been devoted to designing and developing compression algorithms for hyperspectral imagery. Unfortunately, most availa ....etc

Many cryptography arithmetic operations employ the method of modular multiplication. The underlying binary adders in modular multipliers is targeted in this development. The carry-save adder, carry-lookahead adder and carry-skip adder have been studied and compared. They showed interesting features and trade-offs.improved crypto designs are promised by the beneficial details that the design shows.

MODULAR MULTIPLICATION
Modular multiplication is defined as the computation of P=A×B mod M, which are represented using n bits. ....etc

Definition
Every action of the computer takes place in tiny steps, each a billionth of a second long. A simple transfer of data may take only one step; complex calculations may take many steps. All operations, however, must begin and end according to the clock's timing signals.

The use of a central clock also creates problems. As speeds have increased, distributing the timing signals has become more and more difficult. Present-day transistors can process data so quickly that they can accomplish several steps in the time that it takes a wir ....etc

1. INTRODUCTION

Computer chips of today are synchronous. They contain a main clock, which controls the timing of the entire chips. There are problems, however, involved with these clocked designs that are common today.

One problem is speed. A chip can only work as fast as its slowest component. Therefore, if one part of the chip is especially slow, the other parts of the chip are forced to sit idle. This wasted computed time is obviously detrimental to the speed of the chip.

Abstract
SEE-GRID is based on the SEE++ software for the biomechanical simulation of the human eye. The goal of SEE-GRID is to adapt and to extend SEE++ in several steps and to develop an efficient grid-based tool for Evidence Based Medicine'', which supports the surgeons to choose the best/optimal surgery techniques in case of the treatments of different syndromes of strabismus. This paper consists of some speed up curves incase of the calculation of the brainstem pattern wit 45 points. This paper also outline ....etc

Abstract
Traditionally, common processor augmentation solutions have involved the addition of coprocessors or the datapath integration of custom instructions within extensible processors as Instruction Set Extensions (ISE). Rarely is the hybrid option of using both techniques explored. Much research already exists concerning the identification and selection of custom hardware blocks from hardware/software partitioning techniques, but the question of how to best use this hardware within a user system where both coprocessors and datapath ....etc

Mesh Algorithms in Parallel Processing

¢ Parallel processing is processing a task with several processing units, or many processors

¢ Most powerful computers contain two or more processing units that share among themselves the jobs submitted for processing

¢ Several operations are performed simultaneously, so the time taken by a computation can be reduced.

¢ A problem to be solved is broken into a no.of subproblems. These subproblems are now solved simultaneously, each on different processors. The results are then combi ....etc
