Method and apparatus of optimal application mapping on coarse-grained reconfigurable array

摘要

PURPOSE: An application mapping optimizing method in a coarse-grained reconfigurable array and apparatus thereof are provided to improve power efficiency and performance by performing application mapping for the coarse-grained reconfigurable array and by recognizing the structure of a local memory unit. CONSTITUTION: A first mapping result is created by performing application mapping(S10). A data transmission time and a data calculation time are calculated and compared with the first mapping result(S21). When the data transmission time is longer than the data calculation time, a DRG(Data Reuse Graph) which indicates a data reuse relationship is created(S31). An optimized second mapping result is created by repetitively mapping the application based on the DRG(S36).
