LV-Beschreibung

Lehrmethodik inkl. Einsatz von eLearning-Tools

Practical course using Matlab, students work in teams in the PC lab on given exercises

Inhalt/e

This lecture course deals with signal processing algorithms and with appropriate implementation architectures that focus on embedded applications. As a consequence low power consumption and low chip area is of great importance for the regarded architectures. The course starts with a repetition of important signal processing theory and algorithms (Sampling theorem, DFT, FFT, FIR and IIR-filters). In the following the focus lies on implementation oriented issues like fixed point effects and architecture options. We will start with FFT architectures followed by architectures and design issues for fixed point FIR- and IIR-filters. An old, but nowadays more and more important algorithm, the CORDIC algorithm, possible architectures and various applications of the CORDIC will be discussed in the next chapter. Next interpolation and decimation filters and possible low power implementation strategies are regarded. Another important issue in embedded applications is the digital signal generation. We will discuss different architectures for digital signal generators like sine wave generators. Finally we will regard architectures of modern DSPs and FPGAs for embedded applications. In parallel a practical course will be offered, where the effects and architectures are studied with the help of MATLAB/SIMULINK simulations. The course starts with an introduction in MATLAB/SIMULINK and will then focus on practical issues on the appropriate topics covered in the lecture course.

Lehrziel

The SPA practical course is intended to consolidate fundamentals of the lecture (VK) and practice their use. Most exercises target on the use of Matlab, which is a numeric math software which is broadly used for simulation and verification.

Erwartete Vorkenntnisse

Basic digital signal processing knowledge. Basic programming skills.
