Modulo scheduling has the following advantages over the acyclic scheduling approach for control-intensive general-purpose programs. First, modulo scheduling increases performance by maintaining the overlap of loop iterations throughout the execution of the loop. Second, modulo scheduling reduces register pressure by initiating iterations at a consistent rate that is sustainable for the given resources and dependence structure. Third, with the appropriate architectural support, modulo scheduling results in less code expansion because unrolling is required only for optimization, but not to amortize the loss of overlap across the back edge.
