“…Despite the fact that the RVC possesses so many distinctive features in comparison to other existing alternative solutions, the wide usage of the RVC framework for different kinds of data-driven systems, especially multimedia (video, audio, image and graphics) codecs [45,46,47,48,49,50,51], also encouraged us to use the RVC framework to conduct our study on the design and development of secure computing applications in the dataflow programming paradigm.…”

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 functionality (or behavior) of the system become independent of implementation details. The idea is to specify a system so that only intrinsic features of the algorithms are explicitly expressed, whereas implementation choices can then be made only once specific target platforms have been chosen. With this system design approach, one abstract design can be used to automatically create implementations towards multiple target platforms. In this paper, we report our investigations on applying the methodology standardized by the MPEG RVC framework to develop secure computing in the domains of cryptography and multimedia security, leading to the conclusion that the RVC framework can successfully be applied as a general-purpose framework to other fields beyond multimedia coding. This paper also highlights the challenges we faced in conducting our study, and how our study helped the RVC and the secure computing communities benefited from each other. Our investigations started with the development of a Crypto Tools Library (CTL) based on RVC, which covers a number of widely used ciphers and cryptographic hash functions such as AES, Triple DES, ARC4 and SHA-2. Performance benchmarking results on the RVC-based AES and SHA-2 implementations in both C and Java revealed that the automatically generated implementations can achieve a comparable performance to some manually-written reference implementations. We also demonstrated that the RVC framework can easily produce implementations with multi-core support without any change to the RVC code. A security protocol for mutual authentication was also implemented to demonstrate how one can build heterogeneous systems easily with RVC. By combining CTL with Video Tool Library (a standard library defined by the RVC standard), a non-standard RVC-based H.264/AVC encoder and a non-standard RVC-based JPEG codec, we further demonstrated the benefits of using RVC to develop different kinds of multimedia security applications, which include joint multimedia encryption-compression schemes, digital watermarking and image steganography in JPEG compressed domain. Our study has shown that RVC can be used as a general-purpose implementation-independent development framework for diverse data-driven applications with different complexities.

“…This standard is composed of the Reconfigurable Video Codec (RVC) [33], dedicated to the specification of video applications, and Reconfigurable Graphics Codec (RGC) [31], dedicated to the specification of graphic applications (primarily 3D mesh decoders). The RMC framework supplies a normative standard library of multimedia coding tools, the Video Tools Library (VTL) for RVC and the Graphics Tool Library (GTL) for RGC.…”

To cite this version:Jérôme Gorin, Mickaël Raulet, Françoise Préteux. Optimized dynamic compilation of dataflow representations for multimedia applications. Annals of Telecommunications -annales des télécommunica-tions, Springer, 2013, 68 (3-4) Abstract This paper proposes two optimization methods based on dataflow representations and dynamic compilation that enhance flexibility and performance of multimedia applications. These optimization methods are intended to be used in an adaptive decoding context, or, in other terms, where decoders have the ability to adapt their decoding processes according to a bitstream. This adaptation is made possible by coupling the decoding information to process a stream inside a coded stream.In this paper, we use dataflow representations from the upcoming MPEG Reconfigurable Media Coding (RMC) standard to supply the decoding information to adaptive decoders. The benefits claimed by MPEG RMC are a reuse of coding tools between different specifications of decoder and an execution scalability on different processing units with a single specification, which can target either hardware and/or software platforms. These benefits are not yet achievable in practice as these specifications are not used at the receiver side in MPEG RMC. We valid these benefits and propose two optimizations for the generation and the execution of dataflow models: the first optimization takes benefits of the reuse of coding tools to reduce the time to obtain -configure -enforceable decoders. The second provides an efficient, dynamic and scalable execution according to the features of the execution platform. We show the practical impact of these two optimizations on two decoder representations compliant with the MPEG-4 part 2 Simple Profile standard and the MPEG-4 Advanced Video Coding standard. The results shows that configuration time can be reduced by 3 and the performance of decoders can be increased by 50%.

“…digital signal processing, audio and video coding, cryptography, network and packet processing, image analysis, computer graphics. The confluence of these developments has created renewed interest in dataflow programming models, resulting, for instance, in the adoption of a dataflow model (and an associated dataflow programming language) by MPEG and ISO as the foundation for standardizing video codecs [9] and for 3D graphics coding [15].…”

In this paper we address the problem of generating efficient software implementations for a large class of dataflow programs that is characterized by highly data-dependent behavior and which is therefore in general not amenable to compile-time scheduling. Previous work on implementing dataflow programs has emphasized classes of stream processing algorithms that exhibit sufficiently regular behavior to permit extensive compile-time analysis and scheduling, however many real-world stream programs, do not fall into these classes and exhibit behavior that can, for example, depend on the values and even the timing of their input data. Based on an abstract machine model, we partition the problem of implementing such programs in software into three parts, viz. reduction, composition, and code emission, and present solutions for each of them. Using the reference code of an MPEG decoder, we evaluate the resulting code quality and compare it to the state of the art compilers for the same class of stream programs, with favorable results.
