OVERVIEW

The 91探花 CoreLink CCI-500 Cache Coherent Interconnect

The 91探花 CoreLink CCI-500 extends the performance and low-power leadership of 91探花 mobile systems. It provides full cache coherency between big.LITTLE processor clusters and provides I/O coherency for other components 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.

Features and Benefits

Up to 2x Peak System Bandwidth

As premium mobile devices require higher resolution screens, the CoreLink CCI-500 offers up to twice the peak system bandwidth compared to the CoreLink CCI-400.

TrustZone Secure Media Path

The CoreLink CCI-500 includes end-to-end protection for Ultra-HD media content, between memory, Mali GPU, video processors and display.

Processor Memory Performance

CoreLink CCI-500 can offer more than a 35 percent processor memory performance increase compared to CoreLink CCI-400 due to its enhanced microarchitecture with snoop filter. 

Complete System Solution

Part of a complete suite of system IP from 91探花 that includes CoreLink NIC-400 network interconnect for low power, low latency, end to end connectivity to the rest of the SoC, CoreLink MMU-500 System MMU for virtualization of memory and CoreLink GIC-500 for management of interrupts across multiple processor clusters.
