PCI Express High-Performance Reference Design
from Altera Corporation
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 FPGA's 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.
Features
- Ability to showcase high performance (sustained bandwidth) using Altera's 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
Demonstrated Altera Technology
- Stratix® II GX FPGAs
- Altera PCI Express IP cores
