Getting Started

The Arm CoreLink Network Interconnect (NIC) family offers highly configurable topology that enable you to build high performance, optimized, AMBA-compliant SoC connectivity. The CoreLink NIC family is configurable across a wide range of applications from a single bridge component, for example an AHB to AXI protocol bridge, to complex consumer and infrastructure applications.

CoreLink NI-700

NI-700 configurable and scalable Network-on-Chip

Network-on-Chip (NoC) for high-bandwidth accelerators, rest-of-SoC connectivity, and peripherals. A companion to Corelink CI-700 coherent interconnect.

Scalable and highly configurable network-on-chip (NoC)

  • Flexible packetized network-on-chip (NoC) for high-bandwidth accelerators such as GPU and NPU, as well as rest-of-SoC connectivity and peripherals.
  • Suited to infrastructure, as well as consumer and embedded applications.
  • Supports integrated clock controller and power domain settings to manage all the internal P/Q channels

Improved security and performance

  • Adopts the latest Arm architectural features and AMBA protocols that focus on security, performance, reliability, and virtualization.
  • NI-700 supports AHB natively and does not need an AXI to AHB bridge along with integrated QoS features.
  • NI-700 is a natively packetized interconnect and hence inherently more scalable with respect to wiring congestion (variable flit sizes) and timing closure.

Advanced tooling

  • Faster design, configuration, integration, and implementation of complex SoCs for improved system performance, and reduced routing congestion and area.
  • Floorplan and traffic aware AI technology generates and optimizes a NoC speeding time-to-market with improved results.

  • CoreLink NIC-450 Network Interconnect Chip.

  • CoreLink NIC-450

    • Library of key interconnect IP that enables designers to build a scalable and configurable NIC.
    • Available with a tooling automation flow using CoreLink Creator that employs algorithms to accelerate configuration based on design requirements.
    • Enables integrated tooling Socrates DE (licensed separately) for configuring complex interconnect subsystem designs.
    • Includes all NIC-400 features.
    NIC-450 TRM
  • CoreLink NIC-400 Network Interconnect Chip.

  • CoreLink NIC-400

    • Fully configurable, hierarchical, low latency, low power connectivity for AMBA 4 AXI4, AXI3, AHB-Lite and APB interfaces.
    • Scalable for multiple applications from simple single core designs, up to large coherent systems as a companion to CoreLink CCI and CCN coherent interconnects.

NIC-450 and CoreLink Creator

CoreLink Creator with its harvesting flows and enhanced tooling environment provides significant improvements to configure NICs, which decreases time to market.

Functional enhancement in NIC-400r1 with QVN-terminate feature to resolve head-of-line blocking when accessing DRAM provide:

  • Improved support for QVN with DMC controllers using sideband QOSACCEPT signaling, supported in DMC-500 and other 3rd party DMC providers.
  • CPU latency reduction with QoS enhancements, designed and tested with Arm memory controllers such as CoreLink DMC-500.

CoreLink ADB-400

The CoreLink ADB-400 AMBA Domain Bridge is an asynchronous bridge between two components or systems that can be in a different power, clock, or voltage domains.

The ADB-400 supports:

  • An optional configurable destination register for the payload of each channel.
  • Simple reset requirements.
  • A power management interface.
  • Dynamic Voltage and Frequency Scaling (DVFS).
  • Quality of Service (QoS) Virtual Network (QVN).
  • Clock status indication.

The ADB-400 consists of a receiver domain and a transmitter domain. The receiver domain received transfers from the AMBA transmitter and the transmitter domain transfers to an AMBA receiver.

CoreLink XHB-400

The XHB converts AXI4 protocol to AHB-Lite protocol and has an AXI4 requester interface and an AHB-Lite completer interface. 

AXI4 completer interface: This connects to either the AXI4 requester interface of a processor or to an AXI interconnect.

AHB-Lite manager interface: This implements an AHB-Lite manager to drive AHB-Lite subsystems.
