Northwest Logic’s PCI Express 3.0 Solution

Northwest Logic’s PCI Express 3.0 solution, including the Expresso 3.0 Core (PCIe 3.0 core) and Expresso DMA Core, in combination with the Xilinx Kintex-7 Board (KC705) passed all Gold and Interoperability tests at the April 2013 PCI-SIG Compliance Workshop resulting in its certification.  This testing was done with 8 lanes running at 8 Gbit/s.  See PCI-SIG Integrators List on
This further confirms that Northwest Logic’s PCI Express 3.0 solution provides a robust and proven platform for developing PCI Express 3.0/2.1/1.1 based products.  This solution is available for both ASIC and FPGA platforms.


PCI Core and PCI-X Core

The PCI and PCI-X Core has been specifically designed to be easy-to-use and includes the following capabilities:

  • Hides the complexities and timing issues of the PCI-X Bus from the user
