SYSTEM AND METHOD FOR PREFETCHING INSTRUCTIONS AND DATA

Abstract:

Systems and methods for prefetching instructions and data run a program in a test environment, execute a tracing application on the program to collect processor trace data, use the processor trace data to extract a plurality of instruction addresses and a single continuous stack range to be prefetched during a run-time of the program, at initialization of the program, load the extracted plurality of instruction addresses and the extracted stack range, relocate the plurality of extracted instruction addresses and the extracted stack range into the program, and at run-time, prefetch one or more of the plurality of extracted instruction addresses and the extracted stack range during idle time of the program.
