Nowadays, Embedded Systems are key elements of the Avionic Systems. As more and more functions are integrated, their complexity goes increasing. In order to keep mastering this complexity, Avionic Systems Architecture has also evolved so as to minimize the interactions between equipment. This evolution of the Architectures introduced, at the avionic level, the notion of network widely spread in the consumer domain. Our research works aim at accompanying this architectural evolution by minimizing the impact of the technological breakthroughs which were necessary to introduce to support this evolution. For that purpose, we propose an approach which is going to allow us to derisk every new technological brick before its introduction within the Embedded Systems. This introduction can thus be performed by having beforehand defined the conditions as well as the limits of use of every new technology that it is Hardware and/or Software

A Biomedical research seeks good reasoning for solving medical problems, based on intensive work and great debate. It often deals with beliefs or theories that can be proven, disproven or often refined after observations or experiments. The problem is how to make tests without risks for patients, including variability and uncertainty on a number of parameters (patients, evolution of disease, treatments …). Nowadays, medical treatment uses more and more embedded devices such as sensors, actuators, and controllers. Treatment depends on the availability and well-functioning of complex electronic systems, comprising thousands of lines of codes. A mathematical representation of patient or device is presented by a number of variables which are defined to represent the inputs, the outputs and a set of equations describing the interaction of these variables. The objective of this research is to develop tools and methodologies for the development of embedded systems for medical fields. The goal is to be able to model and jointly simulate the medical device as well the human body, at least the part of the body involved in the medical device, to analyze the performance and quality of service (QoS) of the interaction of the device with the human body. To achieve this goal our study focused on several points described below. After starting by defining a prototype of a new global and flexible architecture of mathematical model of human body, which is able to contain required data, we begin by proposing a new global methodology for modeling and simulation human body and medical systems, in order to better understand the best way to model and simulate these systems and for detecting performance and the quality of services of all system components. We use two techniques that help to evaluate the calculated QoS value. The first one calculates an index of severity which indicates the severity of the case studied. The second one using a normalization function that represents the simulation as a point in order to construct a new error grid and use it to evaluate the accuracy of value measured by patients. Using Keil development tools designed for ARM processors, we have declared a new framework in the objective to create a new tester model for the glucose-insulin system, and to define the basic rules for the tester which has the ability to satisfy well-established medical decision criteria. The framework begins by simulating a mathematical model of the human body, and this model was developed to operate in the closed loop of the glucose insulin. Then, the model of artificial pancreas has been implemented to control the mathematical model of human body. Finally a new tester model was created in order to analyze the performance of all the components of the glucose-insulin system.. We have used the suitability of partially observable Markov decision processes to formalize the planning of clinical management

The vision of the emergence of a global environment for the information management where most of the physical object around us will be equipped with processors, communication capabilities and interconnected through various networks forces us to redesign the computing systems. Instead of heavy, monolithic and non-evolutive systems, we must design light, flexible and reconfigurable systems. This work presents a new architecture allowing the conception and development of flexible and reconfigurable operating system kernels for embedded systems

Multimedia applications in general and MPEG in particular are increasingly popular and important workloads for future embedded systems. Multimedia applications are based on algorithms that require a high computational processing power, and high memory and width The high memory bandwidth requirements do not only affect the real-time behaviour of such applications but also their energy consumption. In this thesis, we extracted multimedia specific characteristics based on memory access behaviour of multimedia applications running on embedded system. Hence, based on these characteristics we proposed a new data prefetch mechanism called Pattern-Driven Prefetching (PDP). PDP inspects the sequence of data cache misses and detects recurring patterns within that sequence. According to the patterns being detected, PDP initiates prefetch actions to anticipate future cache misses. PDP demonstrates interesting features both for existing embedded systems, equipped with small cache, as well as for future high performance embedded systems, equipped with large caches

Stereovision allows the extraction of depth information from several images taken from different points of view. In computer vision, stereovision is used to evaluate directly and accurately the distance of objects. In Advanced Driver Assistance Systems (ADAS), number of applications needs an accurate knowledge of the surrounding and can thus benefit from 3D information provided by stereovision. Involved tasks are done in real-time and require a high level of performance that can be provided by hardware accelerators. Moreover, as people safety is affected, the reliability of results is critical. As a result, the hardware solution has to be flexible enough to allow this adaptation. Finally, as the embedded context is considered, the silicon area of the chosen hardware solution must be limited. The purpose of this thesis is to design a processing architecture for stereovision that provides a performance level answering ADAS requirements and a level of flexibility high enough to generate depth maps adapted to various applications. A heterogeneous reconfigurable architecture, named REEFS (Reconfigurable Embedded Engine for Flexible Stereovision), is designed and scaled to answer ADAS requirements and to provide the best trade-off between flexibility, performance and silicon area

In this thesis, we propose a scalable and customizable reconfigurable computing platform, with a parallel full-duplex switched communication network, and a software execution model to redefine the computation, communication and reconfiguration paradigms in High Performance Embedded Systems. High Performance Embedded Computing (HPEC) applications are becoming highly sophisticated and resource consuming for three reasons. First, they should capture and process real-time data from several I/O sources in parallel. Second, they should adapt their functionalities according to the application or environment variations within given Size Weight and Power (SWaP) constraints. Third, since they process several parallel I/O sources, applications are often distributed on multiple computing nodes making them highly parallel. Due to the hardware parallelism and I/O bandwidth offered by Field Programmable Gate Arrays (FPGAs), application can be duplicated several times to process parallel I/Os, making Single Program Multiple Data (SPMD) the favorite execution model for designers implementing parallel architectures on FPGAs. Furthermore Dynamic Partial Reconfiguration (DPR) feature allows efficient reuse of limited hardware resources, making FPGA a highly attractive solution for such applications. The problem with current HPEC systems is that, they are usually built to meet the needs of a specific application, i.e., lacks flexibility to upgrade the system or reuse existing hardware resources. On the other hand, applications that run on such hardware architectures are constantly being upgraded. Thus there is a real need for flexible and scalable hardware architectures and parallel execution models in order to easily upgrade the system and reuse hardware resources within acceptable time bounds. Thus these applications face challenges such as obsolescence, hardware redesign cost, sequential and slow reconfiguration, and wastage of computing power.Addressing the challenges described above, we propose an architecture that allows the customization of computing nodes (FPGAs), broadcast of data (I/O, bitstreams) and reconfiguration several or a subset of computing nodes in parallel. The software environment leverages the potential of the hardware switch, to provide support for the SPMD execution model. Finally, in order to demonstrate the benefits of our architecture, we have implemented a scalable distributed secure H.264 encoding application along with several avionic communication protocols for data and control transfers between the nodes. We have used a FMC based high-speed serial Front Panel Data Port (sFPDP) data acquisition protocol to capture, encode and encrypt RAW video streams. The system has been implemented on 3 different FPGAs, respecting the SPMD execution model. In addition, we have also implemented modular I/Os by swapping I/O protocols dynamically when required by the system. We have thus demonstrated a scalable and flexible architecture and a parallel runtime reconfiguration model in order to manage several parallel input video sources. These results represent a conceptual proof of a massively parallel dynamically reconfigurable next generation embedded computers
