Abstract
Systems and methods for pre-fetching data are disclosed that use a cache memory for storing a copy of data stored in a system memory and mechanism to initiate a pre-fetch of data from the system memory into the cache memory. The system further comprises an event monitor for monitoring events that is connected to a path on which signals representing an event are transmitted between one or more event generating modules and a processor. In some embodiments, the event monitor initiates a pre-fetch of a portion of data in response to the event monitor detecting an event indicating the availability of the portion of data in the system memory.
