In this video format converter example, the system must accept four independent video streams, perform video processing and format conversion and then output the new, transformed, video to at least two different downstream systems at different interfaces and have a PCI express link. This entire video processing system can be implemented in a single quad – using only four transceiver channels since the transmit and receive per channel can support independent data rates. This means that in a Cyclone® IV GX device an entire quad is available for the PCI express link required, and potentially has room for more, such as a gigabit Ethernet link.
