ENHANCING MERGEABILITY OF DATAPATHS AND REDUCING DATAPATH WIDTHS RESPONSIVELY TO REQUIRED PRECISION

摘要

Required precision and information content of datapath signals are used to define functionally safe transformations on data flow graphs. These transformations reduce widths of datapath operators and edges and enhance the mergeability of operators. An algorithm for optimally balancing data flow graph topology to further reduce the data path widths and further enhance mergeability is combined with the above in an iterative algorithm for optimizing DFGs.
