This is the second part of a series of blogs about hardware coherency. In the first blog I introduced the fundamentals of cache coherency: Extended System Coherency – Part 1 – Cache Coherency Fundamentals
This part talks about the implementation of hardware cache coherency and use cases.
Implementing Hardware Coherency
ARM’s first implementations of AMBA® 4 ACE include the ARM® CoreLink™ CCI-400 Cache Coherent Interconnect, ARM Cortex®-A15 and Cortex-A7 processors. These products were first released to our silicon partners in 2011, and we’ve seen the first big.LITTLE™ products come to market in 2013.
