Abstract: Multi-bank Coarse-grained reconfigured processor combines the advantages of high performance and high flexibility, but the existing compiler technology is difficult to make full use of the Multi-bank memory resources, this paper proposes an efficient optimizing algorithm on optimizing the data placement and efficiency of data transformation simultaneously, then we build a model to evaluate the performance, the result shows our approach is capable of optimizing the performance to 2.74x of the state-of-the-art method.
