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 ...

High-Level Synthesis of Dataflow Programs for Signal Processing Systems

Marco Mattavelli, Endri Bezati

The growing complexity of signal processing algorithms and platforms poses significant challenges to design methods and implementation tools. High-level dataflow programs, such as those in MPEG's RVC-CAL language, provide abstraction and the opportunity fo ...

TURNUS: A design exploration framework for dataflow system design

Marco Mattavelli, 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 ...

Reactive Programming Abstractions for Complex Event Logic and Dynamic Data Dependencies

Ingo Maier

A large part of software written today is reactive. In contrast to batch mode systems, a reactive program continuously adapts itself to new input which often requires a substantial amount of engineering. Traditionally, reactive programs are implemented in ...

Profiling of Dataflow Programs Using Post Mortem Causation Traces

Marco Mattavelli, Simone Casale Brunet

The natural representation of data streams, parallelism, and composition has made dataflow an attractive programming model for expressing a wide range of stream and media processing applications, and has led MPEG and ISO to base their latest video coding s ...
