The Arm CoreLink CCI-550 Cache Coherent Interconnect

The Arm CoreLink CCI-550 Cache Coherent Interconnect provides full cache coherency between big.LITTLE processor clusters, Mali GPU, and other agents such as network interfaces or accelerators. It can support up to six AXI Coherency Extensions (ACE) and six memory interfaces for the efficient movement of data. 

Features and Benefits

Fully Coherent GPU Support

One to six ACE ports means CoreLink CCI-550 supports a fully coherent GPU to simplify software development. Hardware coherency enables shared virtual memory and removes the need for time-consuming software-managed cache maintenance.

Complete System Solution

The CoreLink CCI-550 has been designed, tested, and optimized with the latest Arm technology, including the Cortex and Mali processor series, and CoreLink system IP.

Scalability

Highly scalable configuration serves a wide range of applications from premium tablet down to smaller, cost-sensitive designs.

Increased Performance

Microarchitecture for the CoreLink CCI-550 snoop filter provides a 2x snoop hit for bandwidth that extends efficiency across the system.
