learning outcomes and competences to be acquired

Upon successful completion of this course, students will be able to demonstrate knowledge and understanding of:

  • the CPU types,

  • the architectural mechanisms for increasing CPU speed,

  • the CPU datapath,

  • the CPU pipeline,

  • the input/output mechanisms,

  • the peripheral interconnection to the CPU,

  • the data buses,

  • the cache memory operation,

  • the CPU control using assembly instructions

From the laboratory assignments, students will gain the abilities to:

  • use the layer of assembly programming,

  • understand the benefits and drawbacks of using assembly language,

  • develop and debug assembly programs,

  • understand all x86 assembly constructs,

  • understand input/output techniques in the x86 world,

  • understand how to manipulate strings,

  • use the software and hardware interrupts,

  • create interrupt handlers,

  • to visualize graphic elements using assembly.
