FPGA CoaXPress IP Core – Host

Applications

KAYA Instruments’ CoaXPress Host IP Core provides a multi-link receiver solution for high-bandwidth image acquisition. It supports CoaXPress v2.0, with backward compatibility to v1.1, and GenICam-compliant image formats for area-scan, line-scan, multi-ROI and multi-stream applications.

The host IP receives image data from connected cameras and provides a configurable DMA video streaming interface with an internal pixel unpacker for connection to downstream processing or user logic. It supports up to eight video streams and video output widths up to 256 bits per clock per stream.

Coaxial implementations support high-speed link rates up to 12.5 Gbit/s and low-speed control up to 41.6 Mbit/s, depending on the FPGA and configuration. Up to four CoaXPress links are supported as standard, with additional links available on request.

CoaXPress over Fiber support

For optical connectivity, combine the Host IP Core with KAYA Instruments’ Multi-Link Host CoaXPress over Fiber Bridge. The bridge connects the CoaXPress host interface to a compatible 10G Ethernet physical layer through XGMII, enabling fiber-based camera-to-frame-grabber connections.

• Support for one to four parallel fiber links.
• A 10 Gbit/s interface per link with an effective bit rate equivalent to CXP-12 without the coaxial link’s 8b/10b encoding overhead.
• High-speed image-data reception from the device and low-speed control transmission from the host.
• Implementation based on the CoaXPress over Fiber Bridge Protocol v1.0 (JIIA CXPR-008-2021); integration requirements and protocol exceptions are documented in the Host CoF Bridge manual.

The Host documentation includes the CoaXPress IP datasheet and core manual, the dedicated Host CoF Bridge manual, and a Host CoF reference-design guide for AMD/Xilinx FPGAs covering Vivado hardware configuration and Vitis software setup. Select the FPGA, physical layer and optical components for the required link configuration.
