An introductory course regarding embedded systems design. It shows a unified view of hardware and software domains as implementation alternatives based on design exploration and metrics.
The course explores the different trends, components and alternatives according to the final objective. The system level design is introduced by first a description of the different components involved, since integrated circuits design and usage up to software, processors and custom hardware processors.
It also covers design methodologies, optimization techniques and test environments. The course is complemented by practical exercises and laboratory sessions using state of the art technologies.

Material available on the Moodle intranet platform : such as WEB links, slides, articles. Additional material: electronics and programming documentation and boards for lab an project sessions.
Microprocessors architecture and programming.
Digital circuits design.
The course exposes the theoretical bases, the concepts necessary to the development of embedded system, the components. The course is based on one of the references books supported by slides. The students are invited to take part during the course by providing presentations showing design examples, implementation’s alternatives, technological advances, design tools… Laboratory.
The laboratory sessions are illustrated by simple examples. They are of primary importance to allow a comprehension by practice of the concepts necessary to manage architectures based on microprocessors, DSP and circuits based on reprogrammable logic (FPGA/CPLD), the communication, the interfaces, the interaction with the environment, the system level development tools, the details specific to programming languages, and the design flow. During these sessions the student writes a report regarding the work done, measures and results’ analysis. Each group exposes their work to their colleagues.
