Getting Started

Arm CoreLink Interconnect provides the components and the methodology for designers to build SoCs based on the latest Arm AMBA specifications, maximizing the efficiency of data movement and storage, delivering the performance needed at the lowest power and cost. There are three CoreLink Interconnect families, each optimized for their target applications. High performance SoCs with multiple processor clusters would include a Cache Coherent Interconnect, combined with CoreLink Network Interconnect to provide connectivity for the whole SoC.

Highest Performance Coherency

CoreLink Coherent Mesh Network Chip.

CoreLink Coherent Mesh Network

  • Designed for scaling to the highest performance infrastructure applications including networking and servers.
  • Offering scalable system coherency in multi-core heterogeneous processor systems.
  • Highly configurable and scalable CoreLink CMN-600.
  • Previous generation: CoreLink CCN-512, CCN-508, CCN-504 and CCN-502.

Highest Efficiency Coherency

CoreLink Cache Coherent Interconnects

CoreLink Cache Coherent Interconnect

  • Optimized for the highest efficiency coherent applications including mobile big.LITTLE processing.
  • Offering the smallest and lowest power multi-cluster interconnect.
  • Family consists of: CoreLink CCI-550, CCI-500, CCI-400.
  • Find out more.

Network on Chip (NoC)    

CoreLink Network Interconnect Family

CoreLink Network Interconnect

  • Fully configurable for SoC connectivity across all applications.
  • Hierarchical, low latency and low power connectivity.
  • Back plane for smaller, single processor designs.
  • Companion interconnect for I/O coherency and rest of SoC connectivity with CoreLink CCI and CCN.
  • Family consists of: CoreLink NIC-450, NIC-400 and NIC-301.
