High-level dataflow design of signal processing systems for reconfigurable and multicore heterogeneous platforms

Marco Mattavelli, Richard Thavot, Ghislain Roquier, Endri Bezati

The potential computational power of today multicore processors has drastically improved compared to the single processor architecture. Since the trend of increasing the processor frequency is almost over, the competition for increased performance has move ...

Methods to explore design space for MPEG RMC codec specifications

Marco Mattavelli, Richard Thavot, Ghislain Roquier, Endri Bezati, Abdallah Alaaeldin Abdelaziz Elguindy, Simone Casale Brunet

The recent MPEG Reconfigurable Media Coding (RMC) standard aims at defining media processing specifications (e.g. video codecs) in a form that abstracts from the implementation platform, but at the same time is an appropriate starting point for implementat ...

Secure Computing with the MPEG RVC Framework

Marco Mattavelli, Richard Thavot, Junaid Jameel Ahmad

Recently, ISO/IEC standardized a dataflow-programming framework called Reconfigurable Video Coding (RVC) for the specification of video codecs. The RVC framework aims at providing the specification of a system at a high abstraction level so that the functi ...

Design space exploration strategies for FPGA implementation of signal processing systems using CAL dataflow program

Marco Mattavelli, Richard Thavot, Ab Al Hadi Bin Ab Rahman, Endri Bezati, Simone Casale Brunet

This paper presents some strategies for design space exploration of FPGA-based signal processing systems that are specified using the CAL dataflow language. The actor- oriented, high-level of abstraction provided by CAL allows flexible exploration and cons ...

Methodology for the Hardware/Software Co-Design of Dataflow Programs

Marco Mattavelli, Richard Thavot, Ghislain Roquier

New generations of multi-core processors and reconfigurable hardware platforms are expected to provide a dramatic increase of processing capabilities. However, one obstacle for exploiting all the promises of such new platforms is the legacy of current appl ...

Hardware synthesis of complex standard interfaces using CAL dataflow descriptions

Marco Mattavelli, Romuald Mosqueron, Richard Thavot, Julien Dubois

This paper presents a contribution to the development of rapid prototyping tools based on data-flow description. In this context, the efficiency of automatic translator tools from the data-flow description to C and/or HDL are presented using two design cas ...
