The Arm CoreLink CCI-400 Cache Coherent Interconnect
The Arm CoreLink CCI-400 Cache Coherent Interconnect provides full cache coherency between two clusters of multi-core CPUs. It enables big.LITTLE processing and I/O coherency for devices such as the Mali-T600 series GPU, and I/O masters like modem and USB.
Features and Benefits
Widely licensed since 2011, the CoreLink CCI-400 is mature, silicon proven, and has shipped in millions of devices.
The CoreLink CCI-400 supports smaller 2-cluster, 1 or 2 memory interfaces, and is the smallest cache coherent interconnects available from Arm.
Part of a complete suite of system IP from Arm designed, tested, and optimized with the latest Arm technology, including the Cortex and Mali processor series, and CoreLink system IP.
