To achieve a good performance when implementing applications in codesign systems, partitioning and scheduling are important steps. In this paper, a two-phase clustering algorithm is introduced as a preprocessing step to an existing hardware/software partitioning and scheduling system. This preprocessing step increases the granularity in the partition design, resulting in a higher degree of parallelism and a better mapping to the reconfigurable resource. This cluster-driven approach shows improvements in both the makespan of the implementation, and the CPU runtime.
