Actor Merging for Dataflow Process Networks

Marco Mattavelli, Ghislain Roquier, Jani Boutellier

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, Endri Bezati, Ghislain Roquier, Richard Thavot

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

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

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 ...

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

Marco Mattavelli, Endri Bezati, Ghislain Roquier

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 ...

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

Marco Mattavelli, Ghislain Roquier, Richard Thavot

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 ...

RVC: a Multi-Decoder CAL Composer tool

Marco Mattavelli, Ghislain Roquier

The Reconfigurable Video Coding (RVC) framework is a recent ISO standard aiming at providing a unified specification of MPEG video technology in the form of a library of components. The word “reconfigurable” evokes run-time instantiation of different decod ...

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 ...
