Summary, in English

This paper presents a dataflow design methodology and an associated co-exploration environment, focusing on the optimization of buffer sizes. The approach is applicable to dynamic dataflow designs and its performance is presented and validated by experimental results on the porting of an MPEG-4 Simple Profile decoder to the STM STHORM manycore platform. For the purpose of this work, the decoder has been written using the RVC-CAL dataflow language standardized by ISO/IEC. Starting from this high-level representation it is demonstrated how the buffer size configuration can be optimized, based on a novel buffer size minimization algorithm suitable for a very general class of dataflow programs.
