This is the Xilinx Dual Processor Reference Designs suite. The designs illustrate a few differentdual-core architectures based on the MicroBlaze™ and PowerPC™ processors. The designsillustrate various concepts described in the Xilinx White Paper WP262 titled, “DesigningMultiprocessor Systems in Platform Studio”. There are simple software applications includedwith the reference designs that show various forms of interaction between the two processors.

This white paper discusses how market trends, the need for increased productivity, and new legislation have accelerated the use of safety systems in industrial machinery. This TÜV-qualified FPGA design methodology is changing the paradigms of safety designs and will greatly reduce development effort, system complexity, and time to market. This allows FPGA users to design their own customized safety controllers and provides a significant competitive advantage over traditional microcontroller or ASIC-based designs. Introduction The basic motivation of deploying functional safety systems is to ensure safe operation as well as safe behavior in cases of failure. Examples of functional safety systems include train brakes, proximity sensors for hazardous areas around machines such as fast-moving robots, and distributed control systems in process automation equipment such as those used in petrochemical plants. The International Electrotechnical Commission’s standard, IEC 61508: “Functional safety of electrical/electronic/programmable electronic safety-related systems,” is understood as the standard for designing safety systems for electrical, electronic, and programmable electronic (E/E/PE) equipment. This standard was developed in the mid-1980s and has been revised several times to cover the technical advances in various industries. In addition, derivative standards have been developed for specific markets and applications that prescribe the particular requirements on functional safety systems in these industry applications. Example applications include process automation (IEC 61511), machine automation (IEC 62061), transportation (railway EN 50128), medical (IEC 62304), automotive (ISO 26262), power generation, distribution, and transportation. 圖Figure 1.

The standard that governs the design of avioniccomponents and systems, DO-254, is one of the mostpoorly understood but widely applicable standardsin the avionic industry. While information on thegeneral aspects of the standard is easy to obtain, thedetails of exactly how to implement the standard aresketchy. And once an entity develops a process thatachieves compliance, the details of how compliancewas achieved become part of the intellectualproperty of that entity. This white paper focuses onthe details of developing a DO-254 compliantprocess for the design of FPGAs.

The revolution of automation on factory floors is a key driver for the seemingly insatiable demand for higher productivity， lower total cost of ownership，and high safety. As a result， industrial applications drive an insatiable demand of higher data bandwidth and higher system-level performance. This white paper describes the trends and challenges seen by designers and how FPGAs enable solutions to meet their stringent design goals.

dances Act now and you ll be given a free membership to a top Internet firm who is changing people s lives for the better.Mary L. White of LA. stays at home with her children and works just 3 1/2 hours a day... she now earns twice as much money as she did before. Frank Herns Jr. of NY takes 2 vacations a year to the Caribbean and enjoys more time and freedom than ever before. Jane Kennedy of FL fired her boss after 5 months. She finally has the time and money she needs to complete her college education. Craig Garcia of CA tripled his income in just 90 days because took advantage of his free membership.

This article is a very simple introduction writing a Windows Form application for the Microsoft.NET framework using C#. The sample application demonstrates how to create and layout controls on a simple form and the handling of mouse click events. The application displays a form showing attributes of a file. This form is similar to the properties dialog box of a file (Right click on a file and Click on Properties menu item). Since attributes of a file will be shown, the sample will show how to use File IO operations in .NET framework.
