Embedded Systems (SEMP 1)

This course covers two aspects simultaneously: computing and restrictions. It is clear that computer systems have a major impact on our lives, and it is clear that any engineer or scientist should have a basic knowledge of its inner workings. But why should we worry about the restrictions?
Embedded systems, like any computer system, they have to perform a function. But we also have to meet very strict restrictions often:

1. Time constraints: The ABS of a car has to activate the brakes in a very short time to avoid accidents.
2. A reduction in memory requirements and size means lighter devices, more portable and cheaper.
3. Mobile phones, portable media devices and wireless sensor networks often have very strong restrictions on power consumption.
4. Finally, with so few resources, security becomes a very difficult challenge.

In addition, an embedded system has to work in the worst case scenario, should be designed to meet the restrictions even in the worst case.
In this course students will learn to program microprocessor-based embedded systems and hardware design extensions to run in the worst case, considering all the constraints for the design and implementation. We begin with the most basic concepts to soon move to more advanced techniques.
This course provides the theoretical content required for the course "Electronic Systems Laboratory," which is taught in the second semester. The development environment and tools presented in this course will also be used in the laboratory. And this laboratory practices are designed to complement the approach taken in this subject.
We believe in learning by doing. There is no better way to learn how to build an embedded system to building it. Therefore, the course is organized around several projects using the Raspberry-Pi, a computer system the size of a credit card and very cheap that plugs into your TV and a keyboard.
At the end of the course, the student:

1. Efficiently use the tools most widely used development (development tools from the GNU project): GCC compiler, GNU make, binutils, profilers and debuggers.
2. Efficiently use the Linux operating system, including real-time extensions based Xenomai, and be able to describe the inner workings.
3. Be able to write well-structured programs in C, formally correct and efficient, considering hard real-time constraints, memory constraints, and consumption constraints of physical security restrictions.
4. Be able to design and implement complete embedded systems based on the Raspberry-Pi, connecting other hardware components.
