ECMA-407: New Approaches to 3D Audio Content Data Rate Reduction with RVC-CAL

Marco Mattavelli, Claudio Paolo Alberti, Junaid Jameel Ahmad

Inverse problems have only been known in spatial audio for a very short time; their only solution, called "inverse coding" in literature, is essentially based on time-level modeling. Inverse problems, however, unlike parametric coding, require only an init ...

A Methodology For Optimizing Buffer Sizes Of Dynamic Dataflow Fpgas Implementations

Marco Mattavelli, Simone Casale Brunet, Claudio Paolo Alberti, Ab Al Hadi Bin Ab Rahman

Minimizing buffer sizes of dynamic dataflow implementations without introducing deadlocks or reducing the design performance is in general an important and useful design objective. Indeed, buffer sizes that are too small causing a system to deadlock during ...

Exploring MPEG HEVC decoder parallelism for the efficient porting onto many-core platforms

Marco Mattavelli, Simone Casale Brunet, Claudio Paolo Alberti, Damien Jack De Saint Jorre

MPEG High Efficient Video Coding (HEVC) is likely to emerge as the video coding standard for HD and Ultra-HD TV resolutions. The two elements that push HEVC beyond the previous standards are a higher compression efficiency of about a factor of two, and the ...

Reconfigurable media coding: An overview

Marco Mattavelli

This paper provides an overview of the rationale of the Reconfigurable Media Coding framework developed by MPEG standardization committee to overcome the limits of traditional ways of providing decoder specifications. Such framework is an extension of the ...

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 ...

Dataflow Program Analysis and Refactoring Techniques for Design Space Exploration: MPEG-4 AVC/H.264 Decoder Implementation Case Study

Marco Mattavelli, Simone Casale Brunet, Claudio Paolo Alberti, Ab Al Hadi Bin Ab Rahman

This paper presents a methodology to perform design space exploration of complex signal processing systems implemented using the CAL dataflow language. In the course of space exploration, critical path in dataflow programs is first presented, and then anal ...
