Image Data Flow

Description of the image data flow through Coaxlink

The CoaXPress Host Interface extracts the image data from the CoaXPress data stream and store them temporarily in the on-board FIFO buffer together with related metadata such as image size, pixel type, time-stamp...

The image data is extracted as soon as possible from the FIFO buffer ensuring the lowest possible latency.

The Acquisition Gate controls the data extraction. It filters out the image data that doesn't need to be acquired.

The extracted image pixel data flows through the Image Pixel Data Processing chain.

Finally, the DMA engine writes directly the processed and formatted image data into the application buffer.

Note: CoaXPress cameras deliver image data using, typically, a single CoaXPress data stream.
Note: Multi-stream CoaXPress cameras are not supported by this release of Coaxlink!
