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 ...
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.
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 ...
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.
• Designed MSI, MESI and MOESI Coherence Protocols for a multiprocessor system. • Analyzed the Cache Performance for different cache configurations and different number of processors. • Modified the ...
The dividing lines between system buses, system intraconnects, and system interconnects are getting more blurry all the time. And that is, oddly enough, going to turn out to be a good thing in the ...
If multiple devices, such as the CPU and peripherals, access the same cacheable memory region, cache and memory can become incoherent. This is illustrated in Figure 7. Suppose the CPU accesses a ...
