According to CIBC World Markets, Equity Research, theFlat Panel Display (FPD) industry has achieved sufficientcritical mass for its growth to explode. Thus, it can nowattract the right blend of capital investments and R&Dresources to drive technical innovation toward continuousimprovement in view quality, manufacturing efficiency,and system integration. These in turn are sustainingconsumer interest, penetration, revenue growth, and thepotential for increasing long-term profitability for industryparticipants. CIBC believes that three essential conditionsare now converging to drive the market forward

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

FPGAs have changed dramatically since Xilinx first introduced them just 15 years ago. In thepast, FPGA were primarily used for prototyping and lower volume applications; custom ASICswere used for high volume, cost sensitive designs. FPGAs had also been too expensive and tooslow for many applications, let alone for System Level Integration (SLI). Plus, the development

XAPP520將符合2.5V和3.3V I/O標準的7系列FPGA高性能I/O Bank進行連接 The I/Os in Xilinx® 7 series FPGAs are classified as either high range (HR) or high performance (HP) banks. HR I/O banks can be operated from 1.2V to 3.3V, whereas HP I/O banks are optimized for operation between 1.2V and 1.8V. In circumstances that require an HP 1.8V I/O bank to interface with 2.5V or 3.3V logic, a range of options can be deployed. This application note describes methodologies for interfacing 7 series HP I/O banks with 2.5V and 3.3V systems

一些應用利用 Xilinx FPGA 在每次啟動時可改變配置的能力，根據所需來改變 FPGA 的功能。Xilinx Platform Flash XCFxxP PROM 的設計修訂 (Design Revisioning) 功能，允許用戶在單個PROM 中將多種配置存儲為不同的修訂版本，從而簡化了 FPGA 配置更改。在 FPGA 內部加入少量的邏輯，用戶就能在 PROM 中存儲的多達四個不同的修訂版本之間進行動態切換。多重啟動或從多個設計修訂進行動態重新配置的能力，與 Spartan™-3E FPGA 和第三方并行 flashPROM 一起使用時所提供的 MultiBoot 選項相似。本應用指南將進一步說明 Platform Flash PROM 如何提供附加選項來增強配置失敗時的安全性，以及如何減少引腳數量和板面積。此外，Platform Flash PROM 還為用戶提供其他優勢：iMPACT 編程支持、單一供應商解決方案、低成本板設計和更快速的配置加載。本應用指南還詳細地介紹了一個包含 VHDL 源代碼的參考設計。
