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 ...

Audio Spatio-Temporal Fingerprints for Cloudless Real-Time Hands-Free Diarization on Mobile Devices

Danil Korchagin

In this paper, we propose a new low bit rate representation of a sound field and a new method for the corresponding cloudless low delay hands-free diarization suitable for low-performance mobile devices, e.g. mobile phones. The proposed audio spatio-tempor ...

Generation of Hardware/Software Systems Based on CAL Dataflow Description

Marco Mattavelli, Romuald Mosqueron, Richard Thavot, Julien Dubois

This chapter presents a new development of rapid prototyping tools for system design based on data-flow specifications. In this context, the efficiency of tools for the automatic translation from the data-flow programs to C and/or HDL are assessed by means ...

MPEG Reconfigurable Video Coding

Marco Mattavelli

Abstract The currentmonolithic 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 a scheme and specification fo ...

Reconfigurable Video Coding — a Stream Programming Approach to the Specification of New Video Coding Standards

Marco Mattavelli

Current video coding standards, and their reference implementations, are architected as large monolithic and sequential algorithms, in spite of the considerable overlap of functionality between standards, and the fact that they are frequently implemented o ...
