An approach for merging statically schedulable subr egions in dataflow models is pr esented. The approach combines abstr act int erpr etation, loop analysis, and static scheduling of cyclo-static dataflow networ ks. The approach has been implemented in a Java-based tool that per forms automatic classification of dataflow act or s, generat ion of stat ic schedules using constr aint programming, and automatic merging of the finegrained act or s in the subnetwor k into a single, larger -grained actor . The approach is applied to an MPEG-4 SP video decoder implemented in the dataflow act or s language CAL.
