Overview

 
Xilinx provides a fixed netlist LogiCORE PCI-X solution for 64-bit designs running at speeds of up to 66 MHz. By using a Xilinx Real PCI-X solution, designers are provided with an alternative to Application Specific Standard Products (ASSPs) and benefit from the flexibility and cost reduction of an FPGA.These cores are available immediately and support Xilinx Virtex-II and Virtex-E FPGAs. These new cores create an ideal solution for communication systems and storage area network products such as clustered servers, Ultra 3 SCSI and Fibre Channel based RAID arrays, and multi-port Gigabit devices.

 Virtex - II
The Real PCI-X solution enables customers to design fully compliant, high-performance systems by using Xilinx Smart-IP technology to ensure that the critical minimum, maximum and hold timing required for operation at 66 MHz are satisfied. The solution also verifies compliance with PCI-X v1.0 specification through hardware and regression testing, and device characterization using the Xilinx internal test bench that simulates more than six million unique combinations of PCI transactions.

Sam Locke, product development manager at VIEO, Inc., a leading builder, operator, and manager of flexible, high-speed I/O networks, chose the Xilinx Real PCI-X solution for a smart PCI-X adapter device.

"The Xilinx PCI-X core, together with the Xilinx multi-million gate Virtex series FPGA, is enabling VIEO's design of high-performance smart PCI-X adapters that can meet the time-to-market demands and lower development costs required by an ever increasing number of today's applications like Gigabit/10 Gigabit Ethernet and Infiniband Network Interface Cards (NICs)."

Ease of Design

The Xilinx LogiCORE PCI-X Interface has several new features to make the design of a customized PCI-X application easier than ever

  • Simplified user application interface
    • Reduces logic needed for target and initiator designs
    • Retains inherent flexibility of Xilinx PCI interfaces
    • Only one user design required for PCI-X or PCI bus modes and 32-bit or 64-bit bus widths
  • Automatically handles datapath width conversion during 64-bit and 32-bit transactions.
  • Unidirectional datapaths for easier, register-to-register timing.
  • Automatically detects bus mode and bus width, and configures interface to match.
