Abstract
One embodiment of the present invention provides a system that uses references within a first object to prefetch a second object into a cache memory. During operation, the system receives a first cache line containing at least a portion of the first object. Next, the system locates a reference to the second object within the first cache line, and uses the reference to perform a prefetching operation for the second object. In a variation on this embodiment, while performing the prefetching operation for the second object, the system examines the cache memory to determine if the second object is already present within the cache memory. If not, the system performs the prefetching operation for the second object.
