چکیده

This report presents the benefits of using the Model Driven Engineering (MDE) methodology to solve major difficulties encountered by usual high level synthesis (HLS) flows. These advantages are highlighted in a design space exploration environment we propose. MDE is the skeleton of our HLS flow dedicated to intensive signal processing to demonstrate the expected benefits of these software technologies extended to hardware design. Both users and designers of the design flow benefit from the MDE methodology, participating to a concrete and effective advancement in the high level synthesis research domain. The flow is automatized from UML specifications to VHDL code generation and has been successfully evaluated for the conception of a video processing application. Key-words: High Level Synthesis, Design Space Exploration, hardware accelerators, Model Driven Engineering, MARTE standard profile. ∗ [email protected][email protected][email protected] in ria -0 03 11 30 0, v er si on 1 13 A ug 2 00 8 Bénéfices de l’Ingénierie Dirigée par les Modèles pour la Synthèse de Haut Niveau Résumé : Ce rapport présente comment l’Ingénierie Dirigée par les Modèles (IDM) permet de résoudre les difficultés majeures que rencontrent les outils dédiés à la synthèse de haut niveau. Les paradigmes de l’IDM nous servent de base à la définition d’un flot de conception dédié aux applications de traitement de signal intensif. Ce flot de conception génère automatiquement du code VHDL à partir de modélisations en UML. Il permet à la fois à ses utilisateurs et à ses concepteurs de tirer profit de l’utilisation de l’IDM. Son efficacité est évaluée au travers d’une application dédiée au traitement vidéo.

High Level Synthesis of Data Driven

A novel approach to high level synthesis of AsIcs based on a data driven execution model is presented. The synthesis procedure is directed at prodncing highly parallel Aslcs providing high throughput through pipelining. The major benefits of our approach are its potential for higher speed, ease of design, ease of verification and testing.

A System for Data-driven Concatenative Sound Synthesis

In speech synthesis, concatenative data-driven synthesis methods prevail. They use a database of recorded speech and a unit selection algorithm that selects the segments that match best the utterance to be synthesized. Transferring these ideas to musical sound synthesis allows a new method of high quality sound synthesis. Usual synthesis methods are based on a model of the sound signal. It is v...

Using Incremental Consistency Management for Conformance Checking in Feature-Oriented Model-Driven Engineering

Feature-Oriented Model-Driven Engineering (FOMDE) is an approach that lies at the intersection of two complementary paradigms for software construction, Model Driven Engineering (MDE) and Software Product Line Engineering (SPLE). MDE aims at raising the abstraction level of application specification and automating the realization of these abstractions down to the platform level, while SPLE focu...

Fuzzy Logic Based Life Estimation of PWM Driven Induction Motors

Pulse-width modulated (PWM) adjustable frequency drives (AFDs) are extensively used in industries for control of induction motors. It has led to significant advantages in terms of the performance, size, and efficiency but the output voltage waveform no longer remains sinusoidal. Hence, overshoots, high rate of rise, harmonics and transients are observed in the voltage wave. They increase voltag...
