METHODS AND APPARATUS TO DYNAMICALLY INSERT PREFETCH INSTRUCTIONS BASED ON GARBAGE COLLECTOR ANALYSIS AND LAYOUT OF OBJECTS

Methods and apparatus to dynamically insert prefetch instructions are disclosed. In an example method, one or more samples associated with cache misses are identified from a performance monitoring unit in a processor system. Based on sample information associated with the one or more samples, delinquent information is generated. To dynamically insert one or more prefetch instructions, a prefetch point is identified based on the delinquent information.
