Using OCP and Coherence Extensions to Support System-Level Cache Coherence

Open Core Protocol (OCP) [1][2] 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 ...

Memory models for embedded multicore SoCs, Part 4 – Distributed memory and cache

In distributed memory systems, not all cores or processors have the same access to memory; see Figure 4.7. Memory is local to a particular core or processor, with only that processor having direct ...
