A new approach to schedule operations across nested-ifs and nested-loops

This paper presents a new global scheduling algorithm for automatic synthesis of the control blocks of special-purpose microprocessors. The main distinction of the proposed algorithm is that it exploits the inheritances of structured programs. The optimization goal is to maximize the speedup of the processor and minimize the size of the control block. If compared with existing global scheduling algorithms such as Trace scheduling, Tree compaction, and Percolation scheduling, the proposed algorithm consistently achieves better results in terms of the speedup of the processor and the size of the control block.
