Machine Level Programming

• 39 hrs lectures
• 26 hrs pc labs

• 60 pts final exam (written part)
• 12 pts mid-term test (test part)
• 28 pts numeric exercises

Students acquaint with one specific processor architecture. They learn how to use the most important instructions of the processor and its coprocessor, programming of the control structures and they develop learn to develop simple applications (compilation and linking). They learn about calling conventions, some basic operating system services and how to call them. They learn how to practically use this knowledge.
Students learn about processor architecture form the low-level programming point of view, which is one of the very basic skills of an IT professional. They learn how to develop simple applications or libraries in assembler and how to connect them to high-level programming language applications.

To acquaint students with computer programming at the lowest level with focus at chosen processor architecture. To introduce and teach how to actively work with numeral systems, representation of the signed and unsigned numbers, arithmetic in the binary numeral system and representation of the real numbers. To familiarise with a specific processor architecture, its instruction format and addressing modes. To teach to actively work with the common control structures in assembler using given instruction set. To show the connection of programming at a low level and high-level programming via libraries and operating system services. To teach how to use floating point unit to calculate with real numbers.

Elementary knowledge about low-level processor functionality from a programmer's point of view is indispensable for a future IT expert. All programmers should know how does a processor work and how to program it at its instruction level.

Basic knowledge of the C language programming.
