DMA Engine

Transfer over the PCI Express bus of the processed image data to the destination buffer

The DMA Engine transfers directly the processed image data over the PCI Express bus to the destination buffer.

Buffer Filling

The DMA engine delivers image data to GenTL buffers according to rules that are different for line-scan and area-scan image acquisition.

For more informations, refer to Buffer Filling Rules.

Stream Control

Prior to Coaxlink Driver 6.2, the DMA engine was transferring the whole image data as a single 1D entity regardless the 2D structure: the lines of processed image data are concatenated into the destination buffer.

Since Coaxlink Driver 6.2, the DMA engine provides the capability to organize the data differently in the buffer by adding line padding or stripe padding.

For more informations and configuration instructions, refer to Stream Control.

Statistics

The DMA engine performs statistical analysis on the image data flow.

For more informations and configuration instructions, refer to Stream Statistics.
