FAQ

What is the primary function of the EK-U1-VCU129-PP-G?

The EK-U1-VCU129-PP-G is a production-grade PCIe accelerator card built around the Xilinx Virtex UltraScale+ VCU129 FPGA. Its primary function is to deliver hardware-accelerated compute for latency-sensitive, high-bandwidth workloads such as AI inference, video encoding/decoding, and 100G packet inspection. The EK-U1-VCU129-PP-G enables direct host CPU offload via PCIe Gen4 x16 and supports custom RTL integration through Vivado design tools.

Does the EK-U1-VCU129-PP-G support PCIe bifurcation?

Yes, the EK-U1-VCU129-PP-G supports PCIe Gen4 bifurcation modes including x8/x8 and x4/x4/x4/x4, allowing flexible allocation of lanes across multiple endpoints or virtual functions. This capability is implemented in hardware and configurable via BIOS settings and the onboard FPGA configuration bitstream. The EK-U1-VCU129-PP-G maintains full Gen4 signaling integrity under all supported bifurcation configurations.

What memory types and capacities are integrated on the EK-U1-VCU129-PP-G?

The EK-U1-VCU129-PP-G integrates 16 GB of DDR4-2400 (4× 4 GB modules) and 12 GB of RLDRAM3-1600 (2× 6 GB modules), delivering 3.2 Tb/s aggregate memory bandwidth. All memory is directly connected to the VCU129 FPGA's hardened memory controllers with ECC support on DDR4. The EK-U1-VCU129-PP-G does not include LPDDR4 or GDDR6.

Can the EK-U1-VCU129-PP-G operate without external cooling?

No, the EK-U1-VCU129-PP-G requires active cooling: it ships with two 40 mm PWM-controlled fans and thermal sensors on the FPGA, memory, and VRMs. Sustained operation above 65°C junction temperature risks thermal throttling or configuration loss. The EK-U1-VCU129-PP-G is not rated for passive-only operation in standard airflow environments.

What high-speed transceiver interfaces does the EK-U1-VCU129-PP-G provide?

The EK-U1-VCU129-PP-G provides two QSFP28 cages supporting 100G Ethernet (IEEE 802.3bj) and InfiniBand EDR, plus two Samtec FireFly optical mezzanine connectors for custom high-speed I/O expansion. All transceivers are directly connected to the VCU129's GTY transceivers with full protocol stack support in Vivado IP integrator. The EK-U1-VCU129-PP-G does not include SFP+, CXP, or OSFP interfaces.
