A Methodology For Optimizing Buffer Sizes Of Dynamic Dataflow Fpgas Implementations

Marco Mattavelli, Claudio Paolo Alberti, Simone Casale Brunet, Ab Al Hadi Bin Ab Rahman

Minimizing buffer sizes of dynamic dataflow implementations without introducing deadlocks or reducing the design performance is in general an important and useful design objective. Indeed, buffer sizes that are too small causing a system to deadlock during ...

Methodology and Technique to Improve Throughput of FPGA-based CAL Dataflow Programs: Case Study of the RVC MPEG-4 SP Intra Decoder

Marco Mattavelli, Christophe Lucarz, Ihab Mostafa Amin Mohamed Amer, Ab Al Hadi Bin Ab Rahman, Hossam Amer

The specification of complex signal processing systems in hardware by means of HDL is no longer the appropriate way since they are known to be time consuming to design, and less flexible to extend features. Recently, \CAL dataflow language was specified to ...
