CoaXPress Roadmap – Status at November 2017
The current v1.1.1 version of the CoaXPress standard was released at the end of 2015, and provided some clarifications to the well-proven and stable v1.1 dating from 2013.
v2.0 of the standard is currently being worked on and is due to be released Q3 2018. v2.0 will feature a number of enhancements:
- Speed: A key aim of CoaXPress is to support the fastest cameras on the market. CoaXPress currently supports data rates up to 6.25 Gbps per coax. In v2.0, two additional speeds will be added – 10 Gbps (CXP-10) and 12.5 Gbps (CXP-12). This doubles the cable bandwidth, so for example a 4-core cable can provide 4 GBytes/sec of data continuously and reliably from camera to frame grabber.
- Multi-destination: To allow for even faster cameras, v2.0 will also allow a single camera to send data to more than one frame grabber, which could be in different PCs.
- Uplink Speed: The uplink speed will also be doubled for CXP-10 and CXP-12, so allowing trigger rates over 500kHz without requiring a dedicated high speed uplink cable.
- GenICam: Support for the industry standard GenICam will be further enhanced by the addition of GenICam-compliant event packets. This allows the camera to signal events to the PC. Support will be added for 3D-data formats that have been recently added to GenICam.
- Data Integrity: CoaXPress already uses CRC codes to ensure data integrity in the form of bit error detection. v2.0 will add error correction through the use of forward error correction (FEC).
Longer Term Roadmap
A number of other options are being considered for future versions of the standard including an optical physical layer as well as coax. An optical interface is straight forward since the data stream is already in a suitable serialized format.
Speed of course will continue to be improved as technology progresses.
