Study Objective:

Our students have good knowledge of two main aspects of Computer Science: SW and HW. However, these fields are often taught separately. This course aims to link together the knowledge of both of these fields, resulting in the ability to write efficient code for a particular hardware. Students will learn how to predict the maximum code performance and how to achieve it.
