xilinx Zynq-7000 EPP產品簡介

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.

XAPP483 - 利用 Platform Flash PROM 實現多重啟動功能

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。

XAPP482 - MicroBlaze Platform Flash,PROM 引導加載器和用戶數據存儲

　　本應用指南講述一種實用的 MicroBlaze™ 系統，用于在非易失性 Platform Flash PROM 中存儲軟件代碼、用戶數據和配置數據，以簡化系統設計和降低成本。另外，本應用指南還介紹一種可移植的硬件設計、一個軟件設計以及在實現流程中使用的其他腳本實用工具。　　簡介許多 FPGA 設計都集成了使用 MicroBlaze 和 PowerPC™ 處理器的軟件嵌入式系統，這些設計同時使用外部易失性存儲器來執行軟件代碼。使用易失性存儲器的系統還必須包含一個非易失性器件，用來在斷電期間存儲軟件代碼。大多數 FPGA 系統都在電路板上使用 Platform FlashPROM (在本文中稱作 PROM)，用于在上電時加載 FPGA 配置數據。另外，許多應用還可能使用其他非易失性器件(如 SPI Flash、Parallel Flash 或 PIC)來保存 MAC 地址等少量用戶數據，因此導致系統電路板上存在大量非易失性器件。
