ARM Extends Scalability of CoreLink
ARM has added the new interconnect technologies that will help shuttle the data around more quickly. The CoreLink CCN-502 and CoreLink CCN-512 interconnects extend the current family for data center and infrastructure equipment that scales from the edge of the network to the core.
"Our new CoreLink CCN-502 and CoreLink CCN-512 interconnects build on a common architecture, scaling from high efficiency Power-over-Ethernet wireless access points, to high compute density 48-core solutions," said James McNiven, general manager, systems and software group, ARM.
The entire family of CoreLink CCN interconnects, including the CoreLink CCN-504 and CoreLink CCN-508, offer enterprise-class features such as RAS, ECC and advanced QoS to address a wide range of infrastructure SoCs ranging from 1 to 48-cores of CPU that can be coupled with a variety of heterogeneous compute elements. All CoreLink CCN interconnects include native ARM AMBA 5 CHI interfaces providing high frequency, non-blocking data transfers and an integrated Level 3 Cache and Snoop Filter.
CoreLink CCN-502 is an area-optimized interconnect for up to four quad-core processor clusters. Applications may include small cell base stations and sub-10W Power-over-Ethernet wireless access points.
Key benefits and features of the CoreLink CCN-502 include:
- 70% area reduction over CoreLink CCN-504 at 1MB
- Optional, integrated Level 3 System Cache configurable up to 8MB
- High frequency, high performance interconnect supporting up to 0.8Tb/s sustained bandwidth
- 1 to 4 processor clusters including ARM Cortex®-A53 and Cortex-A57 processors with AMBA 5 CHI
- 1 to 4 channels of DDR3/4 memory with DMC-520 supporting 72-bit ECC DIMMs
- Up to 9 1/O coherent ports with AMBA 4 AX14/ACE-Lite interfaces in addition to CPU and DMC ports
The CoreLink CCN-512 is the highest performance solution in ARM's CoreLink CCN family and has been designed for 48-core heterogeneous compute solutions with mix of CPUs, DSPs and accelerators and bandwidths up to 1.8 terabits per second.
Key benefits and features of the CoreLink CCN-512 include:
- Compute Density of up to 12 CPU Clusters (48 cores) including Cortex-A53 and Cortex-A57 with AMBA 5 CHI
- Integrated Level L3 System Cache up to 32MB
- Highest performance CoreLink CCN interconnect supporting up to 1.8Tb/s sustained bandwidth
- 1 to 4 channels of DDR3/4 memory with DMC-520 supporting 72-bit ECC DIMMs
- Up to 24 1/O coherent ports with AMBA 4 AX14/ACE-Lite interfaces in addition to CPU and DMC ports
The new CoreLink interconnects will be added to ARM's Cortex-A57 and Cortex-A53 processor designs, which chip makers license to build 64-bit chipsets for servers, set-top boxes and base stations for cellular networks.
