Infrastructure level systems demand sustainable on-chip bandwidth measured in terabits per second, coupled with ECC and RAS features to maintain system integrity, whilst at the same time supporting high-bandwidth IOs such as encryption engines, PCIe, SATA and multi-gigabit ethernet. To ensure the effectiveness of infrastructure class Arm Cortex processors, the whole system needs to be optimized. The CoreLink CCN Cache Coherent Network product family is specifically designed for such system optimization, enabling high bandwidth Networking and Server applications featuring 4,8 or 12 CPU cluster coherency with configurable level 3 caches.
The CCN interconnect couples tightly with the CoreLink Enterprise DMC supporting DDR4 DRAMs at the same time as managing ECC and providing RAS functionality. CoreLink NIC Non-Coherent Network Interconnect provides low latency peripheral connection, whilst CoreLink Enterprise GIC manages and distributes interrupts across multiple clusters, and even manages MSI(-X) based interrupts from sources such as PCIe. CoreLink SMMU provides IO virtualisation functions by accelerating address translation in hardware. Powerful CoreSight Debug and Trace components complete the offering and are also available for software debug and system optimization.
The net result is a secure, reliable system with non-blocking, free flowing data.
