As consumers, we place many demands on our personal electronics, especially mobile devices. We want them to perform all sorts of tasks efficiently, accurately, and with minimal power consumption. Complex embedded SoCs have largely enabled the functional capabilities of these devices. To ensure that these devices perform at a desired level to accomplish the tasks needed, today’s embedded SoCs must consist of high-performance, heterogeneous, and multi-processing agents. The presence of a large number of data processing agents sharing a memory resource on an SoC requires that the agents maintain some type of locally cached data to reduce the data transportation cost. This, in turn, leads to the requirement for cache coherency to allow agents to cache data during processing and then make it available to the next processing agent.
