Optimized for high-performance enterprise solutions
- The CoreLink CCN-508 enables system coherency targeting mid to high end infrastructure and high-performance computation markets.
- Optimized for compute performance, scaling up to 32 ARMv8 64-bit processors.
- This technology reduces the need to access off-chip memory, saving time and energy, which is a key metric for enterprise customers.
Optimized for ARM Cortex Processors
The CoreLink CCN-508 supports the high performance and efficient cores including the Cortex-A57 and Cortex-A53 processors, and is in the family of ARM CoreLink CCN that support the AMBA 5 CHI standard. This CHI (Coherent Hub Interface) has been developed to support high frequency, non-blocking data transfers between multiple fully coherent processors. It is especially suited for enterprise networking and server applications.
Integrated Low Latency Level 3 Cache
The CoreLink CCN-508 Cache Coherent Network includes an integrated level 3 (L3) cache and snoop filter functions. The L3 cache, which is configurable up to 32MB, extends on-chip caching for demanding workloads and offers low latency on-chip memory for allocation and sharing of data between processors, high-speed IO interfaces and accelerators. The snoop filter removes the need for broadcast coherency messaging, further reducing latency and power.
High Performance DDR3 and DDR4 Memory Interfaces
The CoreLink CCN-508 is optimized to work with the CoreLink DMC-520 Dynamic Memory Controller providing a high-bandwidth interface to shared off-chip memory, such as DDR3, DDR3L and DDR4 DRAM. Enterprise class RAS (Reliability, Availability and Serviceability) features such as ECC for x72 DRAM, TrustZone security and end-to-end QoS (Quality of Service) are integral components of this new memory controller.
