CoreLink CCI-500

The Arm CoreLink CCI-500 Cache Coherent Interconnect

Getting Started

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.

Specifications

 Features Details
 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
 Memory map 32-48 bit physical address width, configurable address map
40, 44, or 48-bit DVM
