CoreLink Network Interconnect Family

Getting Started

The Arm CoreLink Network Interconnect offers highly configurable topology with Network on Chip (NoC)-like properties that enable you to build high performance, optimized, AMBA-compliant SoC connectivity. CoreLink Network Interconnect is configurable across a wide range of applications from a single bridge component, for example an AHB to AXI protocol bridge, to a complex infrastructure that consists of up to 128 masters and 64 slaves in a combination of different AMBA protocols.

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 3^rd 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 slave domain and a master domain. The slave domain received transfers from the AMBA master and the master domain transmits transfers to an AMBA slave.

CoreLink XHB-400

The XHB converts AXI4 protocol to AHB-Lite protocol and has an AXI4 slave interface and an AHB-Lite master interface. 

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

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