Tracter: A Lightweight Dataflow Framework

Philip Neil Garner, John David Scott Dines

Tracter is introduced as a dataflow framework particularly useful for speech recognition. It is designed to work on-line in real-time as well as off-line, and is the feature extraction means for the Juicer transducer based decoder. This paper places Tracte ...

The VELOX Transactional Memory Stack

Rachid Guerraoui, Vincent Gramoli, Michal Kapalka, Aleksandar Dragojevic, Pascal Felber

The adoption of multi- and many-core architectures for mainstream computing undoubtedly brings profound changes in the way software is developed. In particular, the use of fine grained locking as the multi-core programmer’s coordination methodology is cons ...

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 ...

RVC-CAL dataflow implementations of MPEG AVC/H.264 CABAC decoding

Marco Mattavelli, Endri Bezati

This paper describes the implementation of the MPEG AVC CABAC entropy decoder using the RVC-CAL dataflow programming language. CABAC is the Context based Adaptive Binary Arithmetic Coding entropy decoder that is used by the MPEG AVC/H.264 main and high pro ...

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 ...

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 ...

Software Code Generation for the RVC-CAL Language

Ghislain Roquier

The MPEG Reconﬁgurable Video Coding (RVC) framework is a new standard under development by MPEG that aims at providing a uniﬁed high-level speciﬁcation of current and future MPEG video coding technologies using dataﬂow models. In this framework, a decoder ...

TMunit: Testing Transactional Memories

Vincent Gramoli, Pascal Felber

Transactional memory (TM) is expected to become a widely used parallel programming paradigm for multi-core architectures. To reach this goal, we need tools that do not only help develop TMs, but also test them and evaluate them on a wide range of workloads ...

An MPEG RVC AVC Baseline Encoder Based on a Novel Iterative Methodology

Ihab Mostafa Amin Mohamed Amer, Karim Maarouf, Hussein Aman-Allah, Ehab Hanna

With the emergence of new generations of multicore architectures, the need for efficient multimedia algorithm implementations has become critical. This paper describes a new methodology for efficient implementations of algorithms targeting reconfigurable a ...

Overview of the MPEG Reconfigurable Video Coding Framework

Marco Mattavelli, Christophe Lucarz

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 ...
