CPXP-EPx8 PCI Express Endpoint Controller Core with SoC Bridge Extensions for AMBA™ AXI Core

Implements a PCI Express endpoint controller that is compliant with PCI Express Base specification 1.1, including the Transaction, Data Link, and Physical protocol layers.  It is available to act as a bridge to the standard AMBA™ AXI bus.  Other buses such as AMBA™ AHB and Wishbone are available upon request.

The scalable and flexible core has a modular architecture and a high-performance, low-latency design. It supports x8 link widths and offers bi-directional data rate up to 2GB/s. It supports most advanced PCI Express capabilities, including message signaled interrupts, multiple virtual channels, advanced error reporting, end-to-end cyclic redundancy check, power management features, lane reversal and polarity inversion.

The core has an Application Interface (AIF) layer that makes integration significantly easier by relieving the designer from the complexity of transaction layer packet (TLP) handling. This AIF includes a DMA controller and handles the TLP encoding and decoding, and provides an interface to popular system buses, including Wishbone and AMBA™ AHB, AXI, and AXI4.

The external connection interface from the core conforms to the Intel® PIPE specification, ensuring compatibility with any 8-bit PIPE-compliant physical layer (PHY). The core has been successfully used with PHYs from multiple vendors.

The synchronous, latch-free core design was rigorously verified for compliance with the PCI Express specification. The core has been tested for interoperability with multiple motherboards using chipsets from various vendors, and is in use by multiple customers.

The core as delivered is warranted against defects for ninety days from purchase. Thirty days of phone and email technical support are included, starting with the first interaction. Additional maintenance and support options are available.


The core has been verified using Avery’s PCI-Xactor verification tool. Inter-operability has been verified with Intel, nVidia, VIA, and SIS chipsets, and PHYs from Altera and Xilinx has been successfully used by CAST.


The core is available in ASIC (synthesizable HDL) or FPGA (netlist) forms, and includes everything required for successful implementation:
