Extended System Coherency Part 3: Increasing Performance and Introducing CoreLink CCI-500

Monday, April 13th, 2015


System coherency remains an important factor for SoC design starts. The ARM® CoreLink™ CCI-400 has seen great success, over 35 licensees across multiple applications from mobile big.LITTLE, to network infrastructure, digital TV and automotive infotainment. In all these applications there is a need for full coherency for multiple processor clusters, and IO coherency for accelerators and interfaces such as networking and PCIe.


Compared to CoreLink CCI-400, the recently-announced CoreLink CCI-500 offers up to double the peak system bandwidth, a 30 percent processor memory performance increase, reduced system power, and high scalability and configurability to suit the needs of diverse applications. This blog will go into more detail on these benefits, but first I’ll give a quick recap of cache coherency and shared data.
