MODULES  This unit is a module of: 
TEACHING MATERIALS  AULAWEB 
Embedded systems are electronic processing systems based on different kind of microprocessors (microcontrollers, DSP, FPGA, etc.) specifically designed for a single application and are usually integrated (embedded) into the system they control; they cannot be reprogrammed by the user. They are widely used in automation and mechatronics.
At the end of module, the student will be able to: estimate the main requisites, in terms of resources needed (memory, I/O channels, communication bandwidth, computational power) for an embedded applications; identify the peripherals needed for a given application and program them; design and develop code for realtime applications on microcontrollers; use the tools for compiling and downloading code on microcontrollers.
At the end of the module, the student will:
Know how to analyze simple signal filters and control systems represented by block diagrams
Know how to derive the functional dependencies of the input and output signals of interconnected subsystems represented by block diagrams.
Be able to linearize simple continuous time dynamic models, including multivariable ones.
Know how to discretise continuous time dynamic models (including multivariable ones) and derive the pseudo code for their digital implementation.
The module is subdivided in theoretical lessons and laboratory activities (programming embedded systems with the aid of a developer board).
The content of the module is the following one:
Overview on dynamic models in the time and frequency domains with particular reference to linear time invariant (LTI) continuous time models. Scalar models (single input  single output, SISO) and their input  output representation in the time and frequency domains. Introduction to state space models with particular reference to continuoustime LTI models. Multivariable systems (multi input  multi output, MIMO). Solution of continuous time state space LTI models and brief overview of modal analysis with examples (navigation systems, electric motors, etc.).
Block algebra. Reduction and transformation rules of block diagrams for linear operators. Representation of LTI dynamic systems with block diagrams.
Linearization of nonlinear continuous time dynamic systems.
Introduction to the problem of discretization of continuoustime LTI dynamic models. References to the sampling problem. Derivation of discretetime recursive algorithms such as digital realizations of continuoustime LTI dynamic models.
Overview of the pseudocode of signal filtering algorithms and for the realization of PID controllers.
Slides will be available through aulaweb. In general, notes taken during the module and the slides available on aulaweb will be sufficient to prepare the exam.
The following books can be used for further reading on embedded systems:

Details on how to prepare for the exam and the level of knowledge required on each argument will be given during the lessons.
The oral exam will be about the theoretical and programming aspects covered during the lessons, with the aim of evaluating if the student:
