FIFO Buffer
On-board memory dedicated to the temporary storage of image pixel data
The FIFO buffer is a large on-board memory that is entirely dedicated to the temporary storage of image pixel data.
It decouples the CoaXPress data flow from the PCI Express data flow. Temporary dropout of the PCI Express data flow are absorbed by the FIFO buffer while ensuring a reliable CoaXPress data acquisition.
It enables burst-mode CoaXPress data acquisition at the highest data rates regardless the limits of the PCI Express interface.
The total on-board memory is product-dependent.
