We have designed a new electric robotic vehicle controlled by a distributed embedded computer system based on the CAN bus, providing features such as, secured manual driving or autonomous driving, and route planning. These functionalities involve control, image and signal processing algorithms executed under real-time constraints. In order to provide a safe software design and to reduce the dev...

This paper presents a system-level methodology (AAA) for signal and image processing algorithms onto circuit architecture. This AAA (Algorithm Architecture Adequation) methodology is added and implemented in an existing software dedicated to the fast prototyping and optimization of real-time embedded algorithms onto multicomponent architectures. The resulting tool, called SynDExIC, is a free gr...

We present the Algorithm Architecture “Adequation” methodology for the optimized implementation of real-time image processing algorithms on field programmable gate arrays. This methodology is based on a single factorized graphs model, used from the algorithm specification down to the architecture implementation, through optimizations expressed in terms of defactorization transformations. A simp...

VLSI circuits design allows today to consider new modes of implementation for electrical controls. However, design techniques require an adaptation effort that few designers, too accustomed to the software approach, provide. The authors of this article propose to develop a methodology to guide the electrical designers towards optimal performances of control algorithms implementation. Thus, they...

In modern embedded systems, parallelism is a good way to reduce power consumption while respecting the real-time constraints. To achieve this, one needs to efficiently exploit the potential parallelism of the application and of the architecture. We propose in this paper a hybrid optimization method to improve the handling of repetitions in both the algorithm and the architecture. The approach i...

In this paper, we present some pattern recognition algorithms based on the Gabor filtering. We then select an algorithm showing best performance and readiness for a hardware implementation. We focus this paper on the problem of algorithm/architecture adequation. We present a design methodology considering algorithm study and refining, hardware resources, data widths and final cost of the system...

Massively Parallel Computing Systems (MPCS) provide high performance computing generally used to accelerate numerical computation applications. We present a methodology called \Algorithm Architecture Adequation" used to take advantage of the computation power of these systems in the case of real-time applications. With this methodology, application algorithm as well as MPCS are speciied with gr...

Needs for performance on embedded applications will lead to the use of dynamic execution on embedded processors in the next few years. However, complete out-of-order superscalar cores are still expensive in terms of silicon area and power dissipation. In this paper, we study the adequation of a more limited form of dynamic execution, namely decoupled architecture, to embedded applications. Deco...
