Accomplished by well-designed algorithms that keep track of every read and write event, cache coherency is even more critical in symmetric multiprocessing (SMP) where memory is shared by multiple ...

Enabling hardware cache coherence support at OCP cores requires the OCP interface to generate and receive additional coherence messages in order to invalidate cache lines cached at the core side or ...

One of the key challenges in chip multi-processing is to provide a programming model that manages cache coherency in a transparent and efficient way. A large number of applications designed for ...

The reason they want the cache coherency comes down to efficiency and performance. You want to share data between the processors, and if you have hardware cache coherency, then the software doesn’t ...
