Altera PCI Express高性能参考设计

Altera PCI Express高性能参考设计采用Altera  PCI Express MegaCore 功能以及高性能的DMA，它能在FPGA额定内部存储器和系统存储器间传输数据．参考设计包括基于Windows XP的可设定DMA传输的应用软件，应用软件还能测量和显示传输器所达到的性能．参考设计中所用的链式DMA是采用PCI Express编译器所产生的链式DMA案例．Altera提供完整的PCI-SIG兼容的FPGA解决方案，提供各种的x1,x4和 x8 PCI Express应用．解决方案包括可配置的PCI Express IP核，以及用于端点，桥，交换和复合根功能的开发板．解决方案能简便快速实现协议，因此降低了设计风险，缩短了开发时间，使你集中精力在系统设计的核心功能上．

Overview
The PCI Express high-performance reference design uses the Altera PCI Express MegaCore  function and includes a high-performance chaining direct memory access (DMA) that transfers data between the FPGAs internal memory and the system memory. The reference design includes a Windows XP-based software application that sets up the DMA transfers. The software application also measures and displays the performance achieved for the transfers. The chaining DMA used in this reference design is the chaining DMA example generated by the PCI Express Compiler.

主要特性：

Ability to showcase high performance (sustained bandwidth) using Alteras PCI Express x1, x4, and x8 intellectual property (IP) cores with a chaining DMA
Increased customer confidence with documented results of extensive benchmarking performed by Altera
Benchmarking shows close-to-theoretical bandwidth achieved across lane configurations (x1, x4, and x8) and platforms/chipsets
Jump-kick customer designs/performance evaluation
Step-by-step walk-through instructions, complete design files (including Quartus II archive) and Windows XP-based software application provided

Note:

1.DMA = direct memory access
2.ICM = incremental compile module

Altera provides a range of complete, PCI-SIG-compliant FPGA solutions for a variety of x1, x4, and x8 PCI Express applications. The solutions include configurable PCI Express intellectual property (IP) cores and development boards for endpoint, bridge, switch, and root complex functionality. The solutions enable simple and fast protocol implementation, thereby reducing design risk, shortening development times, and allowing you to concentrate on the core functions of the system design.
