Getting Started
Hardware-managed cache coherency is a fundamental technology to scale system performance and enable heterogeneous processing. Hardware cache coherency is a requirement to enable big.LITTLE processing that allows the operating system to choose the right processor for the right job. The Arm CoreLink CCI family of products has been designed into many applications including mobile, tablet, digital TV, set top box, automotive, and low-cost infrastructure. In addition to full coherency for processor clusters with AMBA 4 ACE, the CCI family is also used to provide high performance I/O coherency for accelerators and interfaces using AMBA 4 ACE-Lite.
