Comprehensive Overview of Computer Organization - CS.3843, Fall 2013

This course on Computer Organization (CS.3843) covers essential topics such as information representation, machine-level programming, and processor architecture. Students will learn to convert between different numbering systems (binary, decimal, and hexadecimal), understand IA32 assembly language, and explore Y86 instruction set architecture. Key concepts also include Boolean operations, data types, and logic design. Lecture notes and slides will facilitate understanding of complex material, including practical coding exercises in assembly and C programming.
