Automatic partitioning of behavioral descriptions for high-level synthesis with multiple internal throughputs

This works presents a method for automatically partitioning single process behavioral descriptions (ANSI-C or SystemC) into separate processes under a given global throughput constraint. The proposed method identifies parts in the process with different internal Data Initiation Intervals (DIIs) and partitions it into sub-processes that can in turn be optimized independently. Experimental results show that our proposed method can reduce the overall design area by up to ~38% and on average by ~22% compared to the original single process synthesis. Our method can further reduce the overall design area by on average another ~12% if a design space exploration (DSE) for each newly generated process is performed.
