In summary, the code transformation optimization for loops on the reconfigurable processor has attracted a lot of domestic and foreign research institutions to conduct extensive and in-depth research in the past decade. This is because the loop structure is usually the most time-consuming part in the algorithm. A classic description is that 10% of the code takes 90% of the time, so code optimization for the loop structure can create the most noticeable performance improvement. It should be noted that the above loop-level code transformation method is first used in general-purpose processors. When we apply it to the reconfigurable computing structure, it is no longer independent of the hardware structure, and the mapping efficiency of transformed code on different reconfigurable computing structures is the emerging problem. If insufficient consideration is given to the structural feature of the hardware, the execution efficiency of the code may be significantly affected; otherwise, if hardware structural feature is fully utilized, the efficiency of the code transformation may also have room for improvement.
