Zusammenfassung:In this paper, we propose SWARP, a retargetable preprocessor for exploiting multimedia instructions. The system mixes loop distribution, unrolling and pattern matching to exploit complex multimedia instructions. Contrary to all available systems, it can be extended at the user level. Using with a TriMedia processor we show that our system achieves important good code quality with a set of frequently used loop kernels for multimedia applications.
