Abstract

Methods and an apparatus for generating a speculative helper thread for cache prefetch are disclosed. The disclosed techniques select spawn-target pairs based on profile data and a series of calculations. Helper threads are then generated to launch at the selected spawn points in order to prefetch software instructions (or data) for a single-threaded software application. The generated helper threads are then attached to the single-threaded software application to create a multi-threaded software application.
