Compute Express Link (CXL) FPGA IP

Industry's first FPGA-based hardened CXL IP solution for Type 1, 2, and 3 devices.

First FPGA to pass CXL Consortium Compliance Program (up to 32 GT/s speed) (see Integrators List - Compute Express Link).

CXL Protocol Hard IP Functionality Accelerates a Wide Range of Data-Centric Workloads

  • Accelerated Computing: CXL seamlessly connects FPGAs to accelerators and GPUs, enhancing performance in compute-intensive workloads like AI, machine learning, data analytics, and scientific simulations.
  • Memory Expansion: CXL enables FPGA-based systems to extend their memory capacity by connecting to CXL-compatible memory devices, improving performance in memory-bound applications like memory databases and large-scale data processing.
  • Data Processing: FPGAs with CXL support are used in data processing workloads, including real-time data analytics, financial modeling, and high-frequency trading, where low latency and high bandwidth are critical.
