Actor Merging for Dataflow Process Networks

Marco Mattavelli, Jani Boutellier, Ghislain Roquier

Dataflow process networks provide a versatile model of computation for specifying signal processing applications in a platform independent fashion. This attractive feature of dataflow has lately been realized in dataflow programming tools that allow synthe ...

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 ...

Live demonstration: High level software and hardware synthesis of dataflow programs

Marco Mattavelli, Ghislain Roquier, Endri Bezati

This paper describes and demonstrates a toolchain which enables HW-SW co-synthesis from a single high-level dataflow program. This toolchain does not only enable rapid-prototyping of complex designs, but also provides a complete system integration framewor ...

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 ...

Design Space Exploration and Implementation of RVC-CAL Applications using the TURNUS framework

Marco Mattavelli, Claudio Paolo Alberti, Ghislain Roquier, Endri Bezati, Simone Casale Brunet

While research on the design of heterogeneous concurrent systems has a long and rich history, a unified design methodology and tool support has not emerged so far, and thus the creation of such systems remains a difficult, time-consuming and error-prone pr ...

Synthesizing Hardware from Dataflow Programs

Ghislain Roquier

The MPEG Reconﬁgurable Video Coding working group is developing a new library-based process for building the reference codecs of future MPEG standards, which is based on dataﬂow and uses an actor language called Cal. The paper presents a code generator pro ...

Reconfigurable Video coding on Multicore An overview of its main objectives

Marco Mattavelli, Christophe Lucarz, Ihab Mostafa Amin Mohamed Amer, Ghislain Roquier

The current monolythic and lengthy scheme behind the standardization and the design of new video coding standards is becoming inappropriate to satisfy the dynamism and changing needs of the video coding community. Such scheme and specification formal- ism ...

Dataflow/Actor-Oriented language for the design of complex signal processing systems

Marco Mattavelli, Christophe Lucarz, Ghislain Roquier

Signal processing algorithms become more and more complex and the algorithm architecture adaptation and design processes cannot any longer rely only on the intuition of the designers to build efficient systems. Specific tools and methods are needed to cope ...
