Introduced back in 2011, ACE (AXI Coherency Extensions) grew from the existing AXI protocol to satisfy the cache coherency maintenance demands of SoCs with multi core processors and shared caches in ...

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.

Many people have heard the term cache coherency without fully understanding the considerations in the context of system-on-chip (SoC) devices, especially those using a network-on-chip (NoC). To ...

Demand for ever-higher performance from embedded devices is driving the creation of microprocessors featuring multiple cores. But as core counts rise, shared bus architectures common in some multicore ...

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 ...
