### XCKU060 PCIe Hardware Details and Specifications #### FPGA Model and Configuration The board utilizes the **Xilinx UltraScale Kintex series FPGA model XCKU060-FFVA1156-2-I**, which is designed to support high-speed signal processing applications. This specific FPGA variant offers advanced features suitable for demanding industrial environments[^3]. #### PCI Express Interface Supports **PCIe Gen3 x8 mode**, providing a robust interface with significant bandwidth capabilities essential for data-intensive operations such as those encountered in networked systems or storage solutions[^4]. The implementation ensures compatibility while delivering superior performance. #### Memory Subsystem Equipped with two groups of DDR4 memory modules, each offering: - Capacity: 8 GB per group (totaling 16 GB across both groups) - Bandwidth: Up to 16 GB/s per channel, facilitating efficient handling of large datasets during real-time computations. This configuration enhances overall system throughput by ensuring ample resources are available for caching intermediate results or buffering incoming/outgoing streams without bottlenecks. #### Optical Communication Ports Features dual QSFP+ interfaces capable of supporting up to **two independent 40 Gbps links**. These ports enable flexible connectivity options including but not limited to Ethernet protocols at speeds compatible with modern networking standards. #### Additional I/O Capabilities Includes auxiliary components like an integrated gigabit Ethernet port alongside FMC+(HPC) connectors adhering to VITA 57.4 specifications. Such provisions cater towards specialized peripheral expansions required within certain application domains where additional functionality might be necessary beyond core computational tasks. #### Power Management & System Integration Features Designed with considerations around power sequencing mechanisms that ensure reliable startup sequences along with BPI flash-based firmware loading schemes promoting rapid initialization phases post-power-on events. Furthermore, flexibility regarding clock sources—both internal oscillators as well external reference signals—is provided allowing adaptability based on project-specific requirements. ```python # Example Python code snippet demonstrating how one could interact programmatically using pyopencl library hypothetically interfacing this hardware via OpenCL API calls import pyopencl as cl platforms = cl.get_platforms() for platform in platforms: devices = platform.get_devices(device_type=cl.device_type.FPGA) for device in devices: print(f"Device Name: {device.name}") print(f"Max Compute Units: {device.max_compute_units}") print(f"Global Memory Size: {device.global_mem_size / (1024*1024)} MB") ```
