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 ...

Quasi-Static Scheduling of CAL Actor Networks for Reconfigurable Video Coding

Marco Mattavelli, Christophe Lucarz, Jani Boutellier

The upcoming Reconﬁgurable Video Coding (RVC) standard from MPEG (ISO / IEC SC29WG11) deﬁnes a library of coding tools to specify existing or new compressed video formats and decoders. The coding tool library has been written in a dataﬂow/actor- oriented l ...

High level design space exploration of RVC codec specifications for multi-core heterogeneous platforms

Marco Mattavelli, Christophe Lucarz, Ghislain Roquier

Nowadays, the design flow of complex signal processing embedded systems starts with a specification of the application by means of a large and sequential program (usually in C/C++). As we are entering in the multicore era, sequential programs are no longer ...

An integrated environment for HW/SW co-design based on a CAL specification and HW/SW code generators

Marco Mattavelli, Christophe Lucarz, Ghislain Roquier

The possibility of specifying both SW and HW components using the same language is a very attractive design approach. However, despite the efforts spent for implementing such approach using common programming languages such as C and C++, it has not yet sho ...

IEEE2009

Video coding technology in the last 20 years has evolved producing a variety of diff erent and complex algorithms and coding standards. So far the speciﬁcation of such standards, and of the algorithms that build them, has been done case by case providing m ...

Reconfigurable Video Coding on Multicore: The Video Coding Standard for Multi-Core Platforms

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

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- ...
