Cache Coherent Interconnect for Accelerators (CCIX)

Today's data center throughput is constrained by limitations of computational speed and power consumption. In order to keep up with the growth in data and computational complexity, new approaches to accelerating applications are being explored. One such area of innovation is the acceleration of applications across multiple servers using shared data storage. The Cache Coherent Interconnect for Accelerators (CCIX) is a new chip-to-chip interconnect based on PCI Express® (PCIe®) that allows two or more devices to share data in a cache-coherent manner running at speeds up to 25Gbps. CCIX allows processors in a heterogeneous computing architecture to extend their cache coherency to accelerators, interconnect, and I/O.


  • Faster system integration with pre-integrated PHY, controller, drivers, and verification IP

  • Reduced risk by using silicon-proven PCI Express 4.0 solution

  • Higher quality from applying complete Cadence verification solution
