The Expresso 3.0 Core is part of Northwest Logic's PCIe solution. This solution is designed to achieve maximum PCIe throughput while being easy to use. The Expresso 3.0 Core separately, or in combination with the Northwest Logic DMA Core and DMA Driver, provides the maximum system throughput on a PCIe link. The core is specifically designed for ease of use, including full release packet decoding, complete error handling, automatic handling of PCIe message packets, and comprehensive system debug and link monitoring support. The core is delivered integrated and verified with the target PHY and Expresso (PCIe) testbench. The core is fully compliant with the current version of the PCI Express Base Specification 3.0. The core includes all of the required 3.0 features including physical functions, SR-IOV, and flexible equalization support. To keep clock rates manageable, Northwest Logic also supplies a 256 bit side version of the core. Contact Northwest Logic for more information.


  • PCI Express™ Base Specification Revision 3.0/2.0/1.1 compliant
  • 8.0, 5.0 and 2.5 Gbit/s SERDES support
  • x1, x2, x4, and x8 lane support
  • 32, 64, 128 and 256 bit Core width support
  • SR-IOV support with up to 255 Virtual Functions
