Exercise: every Friday, 12:00-14:00
Material+Forum: ilias (password will be mailed to you)
Required Reading: David A. Patterson, John L. Hennesey - "Computer Organization and Design - The Hardware Software Interface [RISC-V Edition], 2017 Exam: 29 March 2021, 9:00

Course Information

Elective for Bachelor/Master-course computer science, and mandatory for Bachelor/Master-course ESE. This course is intended for M.Sc. and B.Sc. students with a background in digital circuits and programming in C/C++. Students will be introduced to methods of designing computers, which will cover the topics of testing and verification of digital circuits, processor data and control paths, pipelining and parallelism. We will look into the RISC-V instruction set and related CPUs. You will learn to maximize the performance of your computing machinery and how to guarantee the correctness of circuits.

The course will be held in English. Recordings from the last two semester are available for self-paced learning. The exercise will be discussed live every Friday, 12:00-14:00. All session will be recorded and made available via ilias The lecture and exercise will be streamed with Big Blue Button
