64-Bit Computing

The question of why we need 64-bit computing is often asked but rarely answered in a satisfactory manner. There are good reasons for the confusion surrounding the question. That is why first of all; let's look through the list of users who need 64 addressing and 64-bit calculations today: oUsers of CAD, designing systems, simulators do need RAM over 4 GB. Although there are ways to avoid this limitation (for example, Intel PAE), it impacts the performance.

Thus, the Xeon proces ....etc

ABSTRACT
While magnetic and semi-conductor based information storage devices have been in use since the middle 1950â„¢s, todayâ„¢s computers and volumes of information require increasingly more efficient and faster methods of storing data. Among the most promising of the new alternatives are photopolymer-based devices, holographic optical memory storage devices, and protein-based optical memory storage using rhodopsin , photosynthetic reaction centers. This paper focuses mainly on protein-based optical memory storage using the photosen ....etc

BIT for Intelligent system design

The principal of Built-in-test and self-test has been widely applied to the design and testing of complex, mixed-signal electronic systems, such as integrated circuits (IC s) and multifractional instrumentation . A system with BIT is characterized by its ability to identify its operation condition by itself, through the testing and diagnosis capabilities built into its in structure. To ensure reliable performance, testability needs to be incorporated into the early stage of system and product design. Vari ....etc

Introduction

This report presents three main topics we investigated as part of a project to build a Booth encoded multiply/accumulate VLSI chip. The original scope of work included synthesizing VHDL code using the Mentor Graphics tools. Exemplar was the VHDL compiler. Leonardo Spectrum was the synthesizer. Since my team, which included Kevin Delaney, did not meet a Mosis deadline our chip funding was lost. Since we did not actually fabricate a chip, we cannot discuss the success of our results. Likewise, VHDL synthesis using the ....etc
