Camera Link HS Front End: Extracts the video data packets from the Camera Link HS port.
Image Buffer: Stores the video data using the model of video frames.
Horizontal Flip: Performs the line data flip process.
Cropper: Crops the resulting image when used, using a 4-byte resolution.
Lookup Tables: Apply lookup table transformation to the image.
Image Filter 3x3: Apply filter to the image.
Host DMA: Transfers the data from frame grabber into the host buffer memory. This module
will also perform the vertical flip if enabled.
CLHS Camera Implementation
The following figure defines the Xtium CLHS PX8 camera interface as per the Camera Link HS
(CLHS) specification version 1.0. The key parameters are:
A single camera connector (J3) which is a copper hardwired interface with a thumbscrew
locking mechanism – not an optical interface.
Supports the M-Protocol definition of the Physical and Data Link Layer.
There is one command channel to/from the camera.
Supports single connector cameras which have 1 to 7 data Lanes.
