CoreLink CMN-600

Getting Started

The Arm CoreLink CMN-600 Coherent Mesh Network is designed for intelligent connected systems across a wide range of applications including networking infrastructure, storage, server, HPC, automotive, and industrial solutions.  The highly scalable mesh is optimized for Armv8-A processors and can be customized across a wide range of performance points. 

CMN-600 key features

High performance, scalable coherent mesh 

The scalable mesh network can be customized to meet system performance and area requirements. The native AMBA 5 CHI network provides high-frequency, non-blocking data transfers between compute, accelerator, and IO to shared memory resources.  

• Custom, automated design with CoreLink Creator
• Minimum size less than 1mm² in 16nm
• Frequencies greater than 2.5GHz
• Coherent multichip link extends coherency off-chip

Specifications

Agile system cache

Keeping data on-chip greatly improves performance and efficiency. The integrated agile system cache was designed to boost IO throughput workloads such as networking and storage.

• Shared cache for compute, accelerators, and IO.
• Intelligent cache stashing allows accelerators and IO peripherals to allocate critical data to any cache level.
• Far atomic operations supported within the Agile System Cache to enable high frequency updates of shared data such as counters.  
• Programmable on-chip scratch pad RAM partitioning options allow applications to lock down critical data structures such as counters, statistics, and tables.      

Optimized for system performance

The CoreLink CMN-600 has been designed with the CoreLink DMC-620 to provide the highest performance coherent backplane for Armv8-A systems from small, efficient access points to data center solutions maximizing compute density. Notable highlights include:

• 7.5x more compute.
• 5x higher throughput.
• 50% lower latency.
• Sustainable bandwidth exceeding 1TB/s.

CoreLink Creator reduces SoC integration time

CoreLink Creator guides designers through the configuration and creation of an optimized and viable CoreLink CMN-600 interconnect fabric.

It addresses the most complex challenges associated with Interconnect configurability and assembly and enables a faster and easier design that produces a higher quality interconnect.
