ARM CoreLink CCN-508 is the second in a family of Cache Coherent Network products. It enables a fully-coherent, high-performance many-core solution that supports up to 32 cores on the same silicon die, enabling true System on Chip solutions. The CoreLink CCN-508 enables system coherency in heterogeneous multicore and multi-cluster CPU/GPU systems, such as those required for the networking and high-performance computation markets, by enabling each processor in the system to access the other processor caches. This technology reduces the need to access off-chip memory, saving time and energy, which is a key metric for enterprise customers. CoreLink CCN-508 also enables systems based on ARM big.LITTLE™ processing, which delivers both high-performance, required for content creation and consumption, and extreme power efficiency for extended battery life.
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 the second interconnect product to support the AMBA 5 CHI standard. This new 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 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. The CoreLink DMC-520 provides 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.
CoreLink CCN Cache Coherent Network Series
CoreLink CCN-508 Cache Coherent Network is the second in a series of products designed for high performance, power efficient server and network infrastructure products. ARM leadership in scalable, power-efficient multi-core and ‘many-core’ technology already addresses the demand for energy-efficient SoC solutions for use in servers and network infrastructure. The Cache Coherent Network series of products enable our partners to expand their product lines with highly competitive solutions that bring outstanding efficiency to these markets.
