This application note covers the design considerations of a system using the performance
features of the LogiCORE™ IP Advanced extensible Interface (AXI) Interconnect core. The
design focuses on high system throughput through the AXI Interconnect core with F
MAX
and
area optimizations in certain portions of the design.
The design uses five AXI video direct memory access (VDMA) engines to simultaneously move
10 streams (five transmit video streams and five receive video streams), each in 1920 x 1080p
format, 60 Hz refresh rate, and up to 32 data bits per pixel. Each VDMA is driven from a video
test pattern generator (TPG) with a video timing controller (VTC) block to set up the necessary
video timing signals. Data read by each AXI VDMA is sent to a common on-screen display
(OSD) core capable of multiplexing or overlaying multiple video streams to a single output video
stream. The output of the OSD core drives the DVI video display interface on the board.
Performance monitor blocks are added to capture performance data. All 10 video streams
moved by the AXI VDMA blocks are buffered through a shared DDR3 SDRAM memory and are
controlled by a MicroBlaze™ processor.
The reference system is targeted for the Virtex-6 XC6VLX240TFF1156-1 FPGA on the
Xilinx® ML605 Rev D evaluation board
WP369可擴展式處理平臺-各種嵌入式系統的理想解決方案 ：Delivering unrivaled levels of system performance,flexibility, scalability, and integration to developers,Xilinx's architecture for a new extensible Processing Platform is optimized for system power, cost, and size. Based on ARM's dual-core Cortex™-A9 MPCore processors and Xilinx’s 28 nm programmable logic,the extensible Processing Platform takes a processor-centric approach by defining a comprehensive processor system implemented with standard design methods. This approach provides Software Developers a familiar programming environment within an optimized, full featured,powerful, yet low-cost, low-power processing platform.
The Xilinx Zynq-7000 extensible Processing Platform (EPP) redefines the possibilities for embedded systems, giving system and software architects and developers a flexible platform to launch their new solutions and traditional ASIC and ASSP users an alternative that aligns with today’s programmable imperative. The new class of product elegantly combines an industrystandard ARMprocessor-based system with Xilinx 28nm programmable logic—in a single device. The processor boots first, prior to configuration of the programmable logic. This, along with a streamlined workflow, saves time and effort and lets software developers and hardware designers start development simultaneously.
With OpenSSL 0.9.6, a new component has been added to support external crypto devices, for example accelerator cards. The component is called ENGINE, and has still a pretty experimental status and almost no documentation. It s designed to be fairly easily extensible by the calling programs.
With the release of PHP 5 web developers need a guide to developing with PHP 5 to both learn its complex new features and more fully implement the long-standing features on which PHP s success is built. PHP 5 in Practice is a reference guide that provides developers with easy-to-use and easily extensible code to solve common PHP problems. It focuses on providing real code solutions to problems, allowing the reader to learn by seeing exactly what is happening behind the scenes to get your solution. Because a real-life situation will rarely match the book s example problems precisely, PHP 5 in Practice explains the solution well enough that you will understand it and can learn how to truly solve your own problem.
Example to support XML files using MSXML.
=========================================
XML (extensible Markup Language) is a commonly used basis for representing a
huge range of structured data file formats. The specification is maintained by
the World Wide Web Consortium (W3C?. This plugin is intended as an example of
how XML data can be read with a DataPlugin. You can adjust it to meet the needs
of your own XML file format.
After installing the URI file (double click on it), you can find the VBScript
file located at
"C:\Program Files\National Instruments\Shared\USI\plugins\DataPlugins\XML Example"
You can make changes to this file to read your specific XML file.
Lua is a powerful, light-weight programming language designed for extending applications. It is also frequently used as a general-purpose, stand-alone language. It combines simple procedural syntax (similar to Pascal) with powerful data description constructs based on associative arrays and extensible semantics. Lua is dynamically typed, interpreted from bytecodes, and has automatic memory management with garbage collection, making it ideal for configuration, scripting, and rapid prototyping.
The ISO Base Media File Format is designed to contain timed media information for a presentation in a
flexible, extensible format that facilitates interchange, management, editing, and presentation of the media.
This presentation may be ‘local’ to the system containing the presentation, or may be via a network or other
stream delivery mechanism.
The Cryptography API: Next Generation(CNG) is a new and agile framework in Windows Vista, which implements an extensible provider model that allows you to load a provider by specifying the required cryptographic algorithm rather than having to hardcode a specific provider.
Modern C++ Design is an important book. Fundamentally, it demonstrates generic patterns or pattern templates as a powerful new way of creating extensible designs in C++--a new way to combine templates and patterns that you may never have dreamt was possible, but is. If your work involves C++ design and coding, you should read this book. Highly recommended.-Herb Sutter。好書！
