The Arm CoreLink CCI-500 Cache Coherent Interconnect extends the performance and low power leadership of Arm mobile systems. 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-500 offers a scalable and configurable interconnect which enables SoC designers to meet the performance goals with the smallest possible area and power.
|AMBA||AMBA 4 ACE and ACE-Lite|
|ACE slave interfaces||1-4 for fully coherent processors including Arm Cortex|
|ACE-Lite slave interfaces||0-6 for IO coherent devices such as Mali processors, accelerators and IO such as PCIe root complex|
|Memory and System master interfaces||
1-4 memory interfaces
1-2 system interfaces
|Coherency and snoop filter||Integrated snoop filter maintains directory of
processor cache contents, reduces CPU snoops and reduces system power
