KurzbeschreibungThe course will start with logic and finite state machines. These concepts will be applied in practical exercises using FPGAs. Based on this knowledge we will cover the working principles of microprocessors. We will cover combined systems where a micro processor is used for the complex parts and specialized logic on the FPGA is in charge of processing time-critical signals.
LernzielThe goal of this lecture is to give an overview over digital electronic design needed for timing and data acquisition systems used in physics. After this lecture you will have the knowledge to design digital systems based on FPGAs and microcontrollers.

Voraussetzungen / BesonderesWe recommend the students to have taken Analog Electronics for Physicists or to have knowledge of basic analog electronics.

Students (or at least each group of 2 / 3 students) need a laptop computer, preferably running Linux or Windows. For other operating systems we recommend running Linux or Windows on a virtual machine.
