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 ...

Machine learning and artificial intelligence systems are driving the need for systems-on-chip containing tens or even hundreds of heterogeneous processing cores. As these systems expand in size and ...

A new technical paper titled “WARDen: Specializing Cache Coherence for High-Level Parallel Languages” was published by researchers at Northwestern University and Carnegie Mellon University.

More processors on SoCs means more sophisticated cache control. This article describes formal techniques for verifying cache coherency for the ARM AMBA AXI Coherency Extensions (ACE) protocol. Fig 1.

Write-through: all cache memory writes are written to main memory, even if the data is retained in the cache, such as in the example in Figure 4.11. A cache line can be in two states – valid or ...

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 ...
