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.

  • Fully integrated CXL IP solution with PCIe 5.0 x16 (32 GT/s) performance.
  • CXL 2.0/1.1 compliant IP that combines both hard and soft resources:
    • R-Tile Hard IP (PHY IP) reduces logic resourcing and simplifies timing closure.
    • Soft wrapper for added design flexibility and easy integration.
  • Validated with 4th, 5th, and 6th Gen Intel® Xeon® Scalable Processors.
  • Compute Express Link Consortium compatible with CXL certification software (CXL_CV_app).
  • CXL protocol support: CXL.io, CXL.mem, CXL.cache.
  • Device type support: Type 1, 2, and 3.
  • CXL 2.0 IP enhanced with 2.0 features and functionality.
  • Flexible device-attached memory subsystem architecture:
    • Allows FPGA developers to mix and manage different memory types for maximum scalability and application fit.
