This article describes a DDR SDRAM (Double Data Rate Synchronously
Dynamic RAM) controller. The commands of the FPGA-based DDR
SDRAM controller is described in detail. The Verilog HDL is used to implement the R/W operation of the DDR SDRAM. This controler isused to control a 400MHz single channel high-speed, high-precision and large-capacity data acquisition board.

Introduction
The speed and precision of data acquisition system must be sufficiently high to meet the requirements of advanced communication technology development. h ....etc

Data Warehouses, Decision Support and Data Mining

A Data Warehouse is a subject-oriented,integrated,time-variant,non-volatile collection of data used in support of management decision making processes.

Subject-Oriented:-
The data warehouse is organized around the key subjects (or high-level entities) of the enterprise.

Major subjects include
a) Customers
b) Patients
c) Students
d) Products
e) Etc.

Data support :-

Stored collection of diverse data
A solution to data integration problem
Single repository of information
Sub ....etc

t is an encryption system based on the proprietary 40-bit encryption stream cipher algorithm. Became real in the year 1996, now it is widely used in some of the DVD systems. The Content Scramble System key set or the CSS key set, which contains the authentication key, disc key, player key, title key, second disk key set and the encrypted key, are legally outsourced with licences, to different manufactures, to use in their products like the DVD drives, DVD players and DVD movie releases. ....etc

Peer-to-peer computing consists of an open-ended network of distributed computational peers, where each peer shares data and services with a set of other peers, called its acquaintances. The peer-to-peer paradigm was initially popularized by file-sharing systems such as Napster and Gnutella, but its basic ideas and principles have now found their way into more critical and complex data-sharing applications like those for electronic medical records and scientific data. In such environments, data sharing poses new challenges mainly due to the lac ....etc

Project type: System project, tools
Project title: Data Scrambling tool
Abstract
Banks need to protect the identity of its customers. Therefore there is a need to mask all the confidential data, such as, customer name and address, required for its testing. Further masking has to be done in a way such that the integrity of the data in terms of check digits, range checks based on branch code / product types etc. is not lost.
The Data scrambling tool will mask the Production Data. The masked data will reside in a normalize ....etc

Efficient Frequency Domain Selective Scrambling of Digital Video at java

Abstract:
Multimedia data security is very important for multimedia commerce on the Internet such as video-on-demand and real-time video multicast. Traditional cryptographic algorithms/systems for data security are often not fast enough to process the vast amount of data generated by the multimedia applications to meet the real-time constraints. This paper presents a joint encryption and compression framework in which video data are scrambled efficiently in the ....etc

1.1 INTRODUCTION
Encryption of the image and audio data using the conventional methods of cryptography has certain limitations in the cryptographic strength and large computational effort due to huge amount of data and high correlation among pixels. Some of the popular public key encryption methods, such as RSA, El Gamal are not suitable for encryption of large data files and images, because their encryption rate is slow. Moreover, the security of such public key cryptographic schemes relies on the inability to perfo ....etc
