A software method and apparatus for inserting prefetch operations according to data flow analysis. The invention traverses program code to ascertain memory operations and associated address forming operations, and calculates the relative distance between the two operations. If the distance between the two operations is such that a prefetch operation, inserted between the two operations and, in particular to one embodiment, immediately after the address forming operation, would increase the speed of the program when executed, then the prefetch operation is inserted.
