Design Compiler Reference Manual: Optimization and Timing AnalysisPipelining is a technique commonly used to increase the throughput of designs that have deep levels of logic to meet high sampling rate requirements. The pipelining technique partitions blocks of combinational logic into n stages of equal delays, with the stages separated by banks of pipeline registers.
Register balancing improves the performance of the pipeline design, by moving the registers through combinational logic, adding additional registers as needed, to reduce the clock period. In this chapter, you will learn about the following:
• Basic Concepts
• Considering Input and Output Delays
• Handling Designs Having Hierarchy
• Enabling Register Balancing
• Inserting Pipeline Registers in a Design
• Hints and Restrictions
• Resetting Flip-Flops
• Replacing Flip-Flops
This chapter includes example methods of inserting the pipeline registers in a design through HDL and a script to convert simple flip-flops to asynchronously reset flip-flops.

OVERVIEW Established 175 years ago, GLOBUS is a leading retailer in Germany with more than 20,000 employees and nearly 90 locations, including 10 in the Czech Republic. GLOBUS competes in a more than 35 markets, including food, electronics and home improvement, selling more than 100,000 products in each of its stores.
CHALLENGE GLOBUS had been using a proprietary UNIX* system to run its custom-developed ERP applications. Each store location had an expensive server to run its ERP applications, as well as file and print services. With slim profit margins in the food market, the company needed to significantly reduce its IT expenditures, without sacrificing performance or reliability. By moving from a proprietary system to Linux*, GLOBUS sought to reduce both its software and hardware costs. www.novell.com

They allow several threads to run concurrently sharing objects on the heap in the same address space. Each thread has its own frame stack, program counter, local variables and registers. The languages have special syntactical constructs for synchronization. Java has a synchronized statement and synchronized methods, while C# has a lock statement and several attributes that can be applied to classes and methods to control their run-time synchronization behavior.
Although the C# programming languages supports multi-threaded programming directly via special syntax, the underlying thread model is poorly documented and still considered to be part of the library. The Ecma standards for C# [4] and the Common Language Infrastructure [5] contain only a few paragraphs about threads. For example, the lock statement is defined in by a reduction to the library functions Monitor.Enter and Monitor.Exit which are not further specified there. Important issues, such as the order of writes to volatile and non-volatile fields, are just briefly mentioned in two paragraphs in. Hence, a program developer has to rely solely on the class library documentation that comes with Microsoft’s .NET framework Software Development Kit. Unfortunately, that documentation is not very precise with respect to threads, locks and memory issues. Moreover, it is not identical with the (XML) specification of the types that comprise the standard li- braries in [5, Partition IV, Profiles and Libraries]. For example, specifications of Thread.Interrupt, Thread.Suspend and Thread.Resume are not included in.

When you install Windows Vista, you should also decide whether you are upgrading or installing a clean copy on your computer. An upgrade attempts to preserve existing settings; a clean install puts a fresh copy of the operating system on your computer. Installation preparation also involves making choices about your system’s configuration, such as selecting a disk-partitioning scheme. Once you’ve completed all the planning, you are ready to install Vista. This is a straight- forward process that is highly automated and user friendly. To complete the Windows Vista installation, you will need to activate the product through Windows Activation. This process is used to reduce software piracy. After Windows Vista is installed, you can keep the operating system up-to-date with post-installation updates. When you install Windows Vista, you should also consider whether the computer will be used for dual-boot or multi-boot purposes. Dual-booting or multi-booting allows you to have your computer boot with operating systemsSANAKO Media Assistant v. 6.0 User GuideLearning languages is hard work that demands intensive study and practice. However, the right tools can make learning easier and, perhaps most importantly, an enjoyable experience.

It walks through how to use the Java® 2 Platform software to create and run three common types of programs written for the Java platform—applications, applets, and servlets. You will learn how applications, applets, and servlets are similar and different, how to build a basic user interface that handles simple end user input, how to read data from and write data to files and databases, and how to send and receive data over the network.
This tutorial is not comprehensive, but instead takes you on a straight and uncomplicated path through the more common programming features available in the Java platform.

Download Essentials of the Java Programming LanguageT-Splines Maya Plugin Version 1.6After installing the T-Splines plugin, you need to tell Maya to use it.
• On the menu, select Window -> Settings/Preferences -> Plug-in Manager.
• Look for "TSplineShape" (it will be followed by .mll, .so, or .lib; this depends on your operating system). You may need to scroll down to find it.
• Put a check in both the "loaded" and "auto load" boxes. This will load the plug-in and make sure it reloads every time you start Maya.
After you load the plug-in, a "TSplines" menu should appear on the menu bar. Most of what you can do with the plug-in is accessed through this menu. The menu contains links to the T-Spline help pages, the forum, and to many of the operations that you can perform on T-Splines.
Creating a Shelf
To create a shelf with commonly used functions, choose "Create Shelf" from the T-Splines menu. If it's your first time creating the shelf, a new "TSplines" shelf will be added and will be filled with icons. If the shelf already exists, it will re-add any icons that may be missing. Even if you add your own icons to the shelf, you can safely "Create Shelf" again; it will not modify your existing icons. It's a good idea to use "Create Shelf" after upgrading to a new version of the plug-in, as we will probably add new icons on occasion.

To add fuel to the already fast-paced momentum, the company just announced end of fiscal year 2007 revenues that were the strongest in the company’s history—a 22% jump from its respective 2006 results! The thread across all of Keynote’s announcements is its “loud and clear” support for measuring the responsiveness, reliability and customer experience of Web sites using Web 2.0 technologies from the end user perspective.
Specific products addressed in this brief include WebEffective 6.0, Application Perspective 5.0, and Transaction Perspective 8.0. WebEffective 6.0 includes capabilities for assessing user experience on Web 2.0 sites. The new versions of Keynote’s flagship on-demand services for testing and measuring the performance of Web sites Application Perspective 5.0 and Transaction Perspective 8.0 have been enhanced to allow for comprehensive testing and monitoring of AJAX-based and other Web 2.0 applications. Additionally, Keynote has introduced the Keynote Internet Testing Environment (KITE) that is designed to bridge the gap between Web developers and Web operations. KITE provides Web application developers with point and click access to a consistent testing and measurement platform for the entire application lifecycle using IE7.
