This paper presents a novel technique to obtain time schedules for cyclic DFGs representing DSP algorithms mapped onto multiprocessor systems with non-negligible inter-processor communication delays. In this paper, the question of optimizing the input/output delay in the present of inter-processor communication overhead is addressed. The proposed technique operating on the cyclic DFG of a DSP algorithm is designed to evaluate the relative firing times of the nodes by using Floyd- Warshall's longest path algorithm so that the interprocessor communication overhead is taken into consideration to provide an optimal schedule.
