The High But Often Unnecessary Cost Of Coherence

Cache coherency, a common technique for improving performance in chips, is becoming less useful as general-purpose processors are supplemented with, and sometimes supplanted by, highly specialized ...

Using OCP and extensions to support system-level cache coherence

Open Core Protocol (OCP) is a common standard for Intellectual Property (IP)core interfaces. OCP facilitates IP core plug-and-play and simplifies reuse by decoupling the cores from the on-chip ...

Formal Methodology Validates Cache-Coherence Protocol

Moreover, cache coherence is an especially important protocol to verify. A cache-coherence bug could result in a silent data corruption that would disrupt system functionality. A formal tool for ...
