Configurable by Design
The CoreLink Network Interconnect is a highly configurable low latency IP that can be optimized to suit the requirements of a complex SoC using the AMBA protocols.
CoreLink QoS-400 Advanced Quality of Service option provides dynamic bandwidth or latency controlled regulators for the efficient and intelligent management of traffic in complex multimaster designs.
CoreLink QVN-400 QoS Virtual Networks prevent cross-stream or head-of-line blocking through a priority-driven allocation of buffer space to different virtual channels in both the interconnect and the dynamic memory controller (CoreLink DMC-400 or DMC-500).
CoreLink TLX-400 Thin Links option for NIC-400 packetized AXI4 connections, for transmission between switches over fewer signals to reduce wiring congestion and ease timing closure.
Accelerated configuration with Arm CoreLink Creator tooling.
Companion to Cache Coherent Interconnects
CoreLink NIC-400 can be used together with the CoreLink CCN-504 Cache Coherent Network or the CoreLink CCI-400 Cache Coherent Interconnect to extend I/O coherency to larger numbers of masters.
Flexible Topology Adapting to System Requirements
A wide configuration space and flexible topology allows the interconnect to adapt to the system requirements and SoC floor plan. The product can scale from a simple one input one output bridge, all the way up to an SoC wide interconnect with over 100 interfaces. Routing of requests and data is by AXI switches within the fabric. Each link and switch is configurable in width from 32 to 256 bits, allowing the system architect to minimize the number of wires and the interconnect area to meet performance requirements. Flexible data buffering options allow efficient packing and transport of data when changing bus widths.
Advanced Timing Closure Options for High Frequency
Timing closure on small geometry, large SoC design can be accelerated with flexibility on timing closure options within the interconnect. The Network Interconnect offers high flexibility on register placement allowing fine grain tuning in the trade-off between clock speed and latency. Register stages can be configured per-channel and per-direction to isolate long paths.
Support for the Latest AMBA Protocols
Interfaces are fully configurable between AXI4, AXI3, AHB-Lite and APB. Connectivity to cache coherent systems is supported with the CoreLink CCI and CCN families.
