The CQ, CC, and RQ interfaces have a straddle option that allows up to two TLPs to be transferred over the interface in the same beat. This improves the throughput for small TLPs, and when TLPs end in the first half a beat. Straddle can be enabled independently for each of these interfaces during core configuration in the AMD Vivado™ IDE. The straddle option can be used with the Dword-aligned mode only.
