COMPUTER ARCHITECTURE A
Learning outcomes of the course unit
The purpose of the course is to give the students the basic concepts of the modern CPU architectures and computer systems. The course comprises the fundamental knowledge of the programming in language assembly. The concepts are exposed in a general way; when necessary it is made directed reference the architecture of the INTEL CPU family.
