Abstract: An electronic system for multiple agents, both coherent and non-coherent, to communicate with a hybrid cache, the hybrid cache to provide functionality associated with a cache for coherent agents in an outer shareable domain, and to provide functionality associated with a cache for non-coherent agents in a system shareable domain, the functionality provided by tag fields in cache lines stored in the hybrid cache. The tag fields are configured to indicate if a cache line of the hybrid cache belongs to at least one of a logical coherent cache or a logical system cache.
