Abstract
A method and apparatus for converting memory instructions to prefetch operations during a thread switch window is disclosed. In one embodiment, memory access instructions that are already inside an instruction pipeline when the current thread is switched out may be decoded and then converted to the complementary prefetch operations. The prefetch operation may place the data into the cache during the execution of the alternate thread.
