High level synthesis: a data path partitioning method dedicated to speed enhancement

In the field of high level synthesis, a speed improvement of structural designs can be obtained by partitioning the physical data path of the behavioral compilers outcome. This speed improvement is achieved by increasing the number of operations treated simultaneously without appreciable overhead in the silicon area. The authors present a partitioning method based on bus splitting. This method makes use of hierarchical clustering and a description of all the measures needed for partitioning is given
