CoreLink CCI-550

The Arm CoreLink CCI-550 Cache Coherent Interconnect

Getting Started

The Arm CoreLink CCI-550 Cache Coherent Interconnect expands on the successful CoreLink CCI-500.  It provides full cache coherency between big.LITTLE processor clusters and provides I/O coherency for other agents such as Mali GPU, network interfaces or accelerators. CoreLink CCI-550 offers a scalable and configurable interconnect which enables SoC designers to meet the performance goals with the smallest possible area and power and also adds a snoop filter which lowers overall system latency.


Specifications
