BitFlow CoaXPress Frame Grabbers

Cyton-CXP Series

 

 The Cyton-CXP4:  It can be configured in many different ways. It can acquire from one quad CXP-6 camera (total data rate: 25 Gb/S) , or four single link CXP-6 cameras, or anything in between. When acquiring from multiple cameras, each camera is attached to its own virtual frame grabber. This allows independent acquisition and control of each camera.  However, when a four link camera is attached, only one virtual frame grabber is needed.

CoaXPress (CXP) is a simple, yet powerful, standard for moving high speed serial data from a camera to a frame grabber. Video is captured at speeds of up to 6 Gigabits/Second (Gb/S). On the same cable, control commands and triggers can be sent back at 20 Megabits /Second (Mb/S). Power is also supplied to the camera. All this happens over a single piece of industry standard 75 Ohm coaxial cable.

Multiple CXP links can be aggregated to support higher data rates (e.g. four links provide 25 Gb/S of data).

The CXP standard opens the door to applications where cable cost, routing requirements and long distances have prevented the move to high resolution, high speed digital cameras. In many cases, existing coaxial infrastructure can be repurposed for CXP with very low installation costs.

About the Cyton-CXP

Virtual Frame Grabber

The Cyton-CXP4 can be configured in many different ways. It can acquire from one quad CXP-6 camera (total data rate: 25 Gb/S) , or four single link CXP-6 cameras, or anything in between. When acquiring from multiple cameras, each camera is attached to its own virtual frame grabber. This allows independent acquisition and control of each camera.  However, when a four link camera is attached, only one virtual frame grabber is needed.

Cyton-CXP StreamSync

The StreamSync system consists of an Acquisition Engine and a Buffer Manager. The StreamSync system was first released on the Cyton-CXP and is a departure from previous BitFlow frame grabbers. The StreamSync system is a start-from-scratch complete redesign of the acquisition and DMA parts of a frame grabber. BitFlow used it years of experience in this area to design a next generation, super efficient capture system.

StreamSync Features

  • Efficient support for variable sized images with fast context switches between frames
  • Per frame control of acquisition properties (AOI specifically)
  • Hardware control of image sequencing
  • Enhanced debug capabilities
  • Efficient support for on-demand buffer allocation (Genicam model)
  • Gracefully recovery from dropped packets (either on the input side or the DMA side)

CoaXPress High Speed Uplink

The Cyton-CXP has an optional fifth CXP connector that can run the full 6.25 Gb/S from the frame grabber to the camera. The CoaXPress standard is still evolving, but the need for this high speed uplink has already become apparent. The demands for bulk uploads to the camera, and precise trigger accuracy have already outstripped the current 20 Mb/S uplink specification. The Cyton-CXP is fully ready when the new CXP standard is released that defines when and how this uplink will be used.

PCI Express Gen 2.0 Interface

The Cyton-CXP has a Gen 2.0 x8 PCI Express bus interface. The Gen 2.0 PCIe bus doubles the data rate of the Gen 1.0 bus while using the same footprint and connectors. The Bitflow_CytonCXPCyton-CXP is fully backwards compatible with Gen 1.0 motherboards, though the data rate will be halved. However, Gen 2.0 motherboards have been shipping for a few years and will be the norm on almost all motherboards looking forward. The board will work in any slot that it fits in. This means not only x16 and x8 slots, but also, as is becoming the trend, x4 and x1 slots that use x16 connectors. Performance will be degraded in x1 and x4 slots, but the board will work fine in applications that don’t require maximum data rate.

Camera Control and I/O

The Cyton-CXP can acquire fixed or variable size images and features a programmable ROI (Region Of Interest) sub-windowing capability. The Cyton-CXP fully supports the Bitflow_CytonCXPCoaXPress 1.0 specification for one high speed trigger and either general purpose I/O signals to the camera and from the camera. These I/O signals can be routed to/from many internal and external destinations, the flexibility of the routing is unprecedented in the industry. In addition, there are separate hardware I/O signals which can be connected to/from external source. Finally each CXP camera has a fully set of these signals which can be run independently. The Cyton-CXP board, as with our past interface products, supports not only simple triggering modes but also complicated, application-specific triggering and control interactions with your hardware environment.

Application Support

Adding the Cyton-CXP to your application is simple with our SDK, which supports both 32-bit and 64-bit operating systems.Bitflow_CytonCXP Applications can be developed using C/C++/.NET and our sophisticated buffer management APIs. In addition, free drivers can be download from our web site for most 3rd party machine vision packages. The Cyton models are software compatible with each other, as well as with all the other current BitFlow frame grabbers. This makes migrating applications from Camera Link or analog to CXP simple and quick.
