Abstract
A system includes an internal memory configured to store data, a memory access controller, logic, and a processor. The memory access controller is operable to read data from a peripheral device in response to an event external to the system, write the data to memory external to the system and forward the data or a portion of the data to the internal memory. The logic is operable to track which portion of the data is stored in both the external memory and the internal memory. The processor has one or more caches logically and physically separated from the internal memory. The processor is operable to retrieve the data forwarded to the internal memory and use the retrieved data to begin servicing the event.
