Global Loop Transformation Steering
As motivated, the reorganisation of the loop structure and the global control flow across the entire application is a crucial initial step in the DTSE flow Experiments have shown that this is extremely difficult to decide manually due to the many conflicting goals and trade-offs that exist in modern real-life multi-media applications. So an interactive transformation environment would help but is not sufficient. Therefore, we have devoted a major research effort since 1989 to derive automatic steering techniques in the DTSE context where both “global” access locality and access regularity are crucial.
