Improved HW/SW partitioning algorithm on efficient use of hardware resource

This paper improved the greedy partitioning algorithm targeting hardware resource use efficiency in traditional partitioning algorithms. In the improved algorithm, introduced a guiding function, which decided by four factors: the criticality, saved time, frequency and area of tasks. The improved algorithm can not only improve the resource use efficiency, but also pay attention to the task on the critical path, which can maximized the performance of the system. On the basis of this, the designer can design the system with low power methods, minimized the power consumption as well as satisfy the system performance.
